(I prefer to ignore the specific details of the implementation and only discuss the idea in general. Because debating the details feels like "too soon; I need to be sure about the higher level first".)

There is a profound difference between building "commons of knowledge" and a "discussion website". In some sense, they are the opposite of each other. Discussion websites, by their nature, attract people who have a preference for discussion. Curiosity seeks to annihilate itself, but social interaction seeks to grow and persist. And if people who feel that the debate is no longer productive start leaving, well, those who don't mind will become the new norm.

But how do you build the commons of knowledge without having the discussion first? How would people contribute? How would they point out the mistakes? How would they conclude whether the supposed "mistakes" are actual mistakes or not? How would they coordinate in time, so that the published piece of knowledge is reviewed now, and the author can read the responses and update the text now? (as opposed to e.g. someone randomly pointing out an error ten years later, and the original author no longer being active)

Seems to me that successful knowledge-oriented websites, such as Wikipedia and Stack Exchange, solve this problem by separating the knowledge from the discussion. There are different ways to do it.

On Wikipedia, the article presents the "final answer", and the whole discussion happens on the Talk page. (There is typically one Talk page per article, but if the discussion grows unusually long, the older parts are gradually moved into separate read-only Archive pages.) If someone believes they have found a mistake in the article, they edit the article, and optionally explain the reason on the Talk page. If someone else believes they were wrong, they revert the changes in the article, and optionally explain their reasons on the Talk page. This sometimes leads to an "edit war", when various solutions are implemented, for example the page can be "locked" so the ordinary users can't edit it anymore, and all they can do is argue for their case on the Talk page; only privileged remain able to edit the article.

On Stack Exchange, each user can provide their own answer to the question, and all answers are displayed below the question; the ones with the most votes are displayed first. There is further an option to write a short comment below the question or an answer, and to upvote the comment. (The comment structure is linear, not hierarchical.) To prevent the growth of the discussion, only a limited amount of text is displayed immediately; displaying the remaining text requires further user action. For example, if there are more than N answers, only the highest upvoted N answers are displayed below the question; the remaining ones are moved to page 2 or more. Similarly, if there are more than M comments below a question or an answer, only the highest upvoted M comments are displayed, unless the user explicitly clicks "show more comments". Together this means that regardless of the number of answers and the number of comments, the user clicking on the question still receives a relatively short page, containing the most relevant things. Furthermore, debate that is not strictly on-topic is discouraged, the content of such debate is frequently removed, and the users are advised to debate their opinions on a chat, outside the question-and-answers area.

We can't copy either model directly. Less Wrong is neither an encyclopedia nor a Q&A website. (We discuss things that sometimes don't have official names yet; and we often provide insights and opinions without being asked first.) We are more like a blog, or maybe a news site. But blogs are personal (worked well while Eliezer was writing the original Sequences) or for a predefined group of authors; they don't scale well. A the purpose of news is typically to maximize paperclips... ahem, pageviews... which is best achieved by techniques contrary to the goal of developing and spreading rationality. (I suspect that the next step in the online news business will be websites with fake news generated automatically using machine learning and A/B testing. Using thousands of different domain names, to make it impossible to write a domain-name filter; generating enough content to keep all domains active and seemingly different. Also, automatically generated comments below the articles. And automatically generated replies to humans who get fooled by the system.)

Seems to me these would be reasonable guidelines for a good solution:

• Keep the "final product" and the "intermediate products" unambiguously separated, in a way that clearly communicates to the reader's System 1. Preferably, each of them on a different domain name, with different design. Separate "LW, the sacred tome of rationalist knowledge" from "LW, where highly intelligent people procrastinate".

• The change from the "intermediate" to the "final" state must always be done by a conscious decision of a group of trusted people. (It is not necessary to make all of them approve each change, more like: any two or three of them may promote the content, and then any one of them can veto the change, and if that happens, then all of them will debate behind the closed doors until they reach a consensus.) No amount of votes is enough to automatically promote an article; and no amount of karma is enough to automatically promote a person to the trusted circle. On the other hand, members of the trusted circle are publicly known. And within the trusted circle, they can review all other other's actions and votes.

• Changing the article from the "intermediate" to the "final" state may include asking the original author to rewrite it (or to consent with someone else's rewrite). Thus we would avoid the dilemma of "some part of this article are low-quality and lenghty, but here are a few really valuable points, so maybe the cost-benefit analysis suggests we promote it anyway". Nope, just rewrite it to keep the good parts and remove the bad parts; it will take you an afternoon, and the updated version will be there displayed to everyone for years.

• Promoting the article to the "final" state does not mean promoting comments below it to the "final" states. First, no comments should get promoted automatically; and second, most comments should not be promoted at all. So, the "final" website should just display the article without the comments (but maybe with a link to the original discussion). If some comments are considered worthy enough to be canonized along with the article, they could become a part of the article itself, e.g. either by fixing the mistake, or adding a footnote. Paraphrasing Dijkstra, we should not regard LW comments as "lines produced" but as "lines spent".

• New visitors to the website should be directed to the "final" version foremost, and to the "intermediate" version only as a secondary option. So unless they have a specific plan, they will read some parts of the "final" version before they start participating in the "intermediate" section. In other words, having people debating on LW without reading the Sequences first is a result of bad web design.

EDIT:

In some sense, having LW separated into forum and wiki is a partial step in this direction, but it differs from this proposal in many important ways:

The highest-value content stays in the forum section, along with the low-value content. (It is merely linked from the wiki.) Thus, at least to my System 1, the good articles and the bad articles are connected more than any of them is with the wiki. Also, all comments, whether good or bad, remain connected with the good articles.

When new people visit the page for the first time, the first thing they see is... a description that seems like a Wikipedia article stub; four recent articles; and four non-recent articles. Not good. The title page should contain at least 95% of nicely designed hand-picked best content, and only a small link towards the discussion somewhere in the corner.

On the other hand, a technically simple implementation of my suggestion would be to create another website -- which could be technically a wiki, but it absolutely shouldn't look like one; all the wiki-related buttons should be hidden from the average observer, and only available for the "inner circle" -- and copy the hand-picked best articles there. For the average visitor, there would be no way to post anything; only to click the links and read the contents. Occassionally, a link would point them towards a relevant discussion on LW, but to their System 1 that would be obviously a link to an external website, with a different design. (The "inner circle" would have a Slack debate somewhere, where they would talk about which articles deserve to be copied. All contributors to LW would have to consent in advance with the possibiity of having their article copied to the other website -- and removed from LW, to avoid having duplicates.)

Interesting proposal. Can you say something about who would be able to see the individual ratings of comments and users? What do you see are the pros and cons of this proposal vs other recent ones.

the site will never rate a response higher than its parent, or a top-level comment higher than the post it replies to

What's the reason for this? It seems to lead to some unfortunate incentives for commenting. Suppose someone posts a new and exciting idea and you find a subtle but fatal flaw with it. If you comment right away then people will realize the flaw and not rate the post as high as they otherwise would, which would limit the rating of your comment, so the system encourages you to wait until the post is rated higher before commenting.

More generally this feature seems to discourage people from commenting early, before they're sure that the post/comment they're responding to will be rated highly.

Content ratings above 2 never go down, except to 0; they only go up. Thus, the content in these circles can grow but not shrink, to create a stable commons.

This seems to create an opening for attack. If an attacker gets a high enough rating to unilaterally push content from 2 to 3 stars, they can sprinkle a lot of spam throughout the site, rate them to 3 stars, and all of that spam would have to be individually marked as such even if the attacker's rating is subsequently reduced.

Trust flows from these users using some attack resistant trust metric.

Can you point to an intro to attack resistant trust metrics. I think a lot of people are not familiar with them.

Downvoting sprees from untrusted users will thus be annoying but ineffective.

Why would it be annoying? I'm not sure I understand what would happen with such a downvoting spree.

This is seeking a technological solution to a social problem.

The proposed technological solution is interesting, complicated, and unlikely to ever be implemented. It's not hard to see why the sorts of people who read LW want to talk about interesting and complicated things, especially interesting and complicated things that don't require much boring stuff like research -- but I highly doubt that anyone is going to sit down and do the work of implementing it or anything like it, and in the event that anyone ever does, it'll likely take so long that many of the people who'd otherwise use LW or its replacement will lose interest in the interim, and it'll likely be so confusing that many more people are turned off by the interface and never bother to participate.

If we want interesting, complicated questions that don't require a whole lot of research, here's one: what exactly is LW trying to do? Once this question has been answered, we can go out and research similar groups, find out which ones accomplished their goals (or goals similar to ours, etc.) and which ones didn't, and try to determine the factors that separate successful groups from failed ones.

If we want uninteresting, uncomplicated questions that are likely to help us achieve our goals, here's one: do we have any managers in the audience? People with successful business experience, muaybe in change management or something of that nature? I'm nowhere near old or experienced enough to nominate myself, or even to name the most relevant subdomains of management with any confidence, but I've still seen a lot of projects that failed due to nonmanagers' false assumption that management is trivial, and a few projects in the exact same domain that succeeded due to bringing in one single competent manager.

As Anna Salamon set out, the goal is to create a commons of knowledge, such that a great many people have read the same stuff.

There's already a lot of stuff from the post-LW fragmentation that a great many people have read. How about identifying and compiling that? And since many of these things will be spread out across Tumblr/Twitter/IRC/etc. exchanges rather than written up in one single post, we could seed the LW revival with explanations of them. This would also give us something more interesting and worthwhile to talk about than what sort of technological solution we'd like to see for the social problem that LW can't find anything more interesting and worthwhile to talk about than what sort of technological solution we'd like to see for the social problem that LW can't find anything interesting or worthwhile enough to get people posting here.

Interesting proposal.

I would suggest one modification : a "probation" period for contents, changing the rule "Content ratings above 2 never go down, except to 0; they only go up." to "Once a content staid for long enough (two days? one week?) at level 2 or above, it can never go down, only up" to make the system less vulnerable to the order in which content gets rated.

I should like to see a monthly "magazine" of the most interesting posts and comments, and a compilation of the science links and topics under sub headings, like "life extension", cancer and health, seti and cosmology, sim and modeling, etc.

You would then be able to graze articles and hit highlights of your favorite science , and be able to send a link to friends you might think are interested in some included topic, and they would get some exposure to related info too.

Top articles could be published here in discussion to hammer out any problems, then finished articles would be consolidated into the 'magazine", and loaded to the wiki, and/or front page, if relevant.

I don't really understand the reasons behind a lot of the proposed site mechanics, but I've been toying around with an idea similar to your slider, but for a somewhat different purpose.

Consider this paradox:

1. As far as I can tell, humor and social interaction is crucial to keeping a site fun and alive. People have to be free to say whatever is on their mind, without worrying too much about social repercussions. They have to feel safe and be able to talk freely.

2. This is, to some extent, at odds with keeping quality high. Having extremely high standards is one of the things that makes LW valuable, and gives it such a high signal to noise.

So, how do we cope with this dichotomy? One way is to allow users to either submit a comment/post to the outer circles, or to an inner one. I think this is part of what we were going for with the Discussion/Main dichotomy, but no one posted to Main, so people don't even check it anymore. But, because of our quality standards for Discussion, people also hadn't felt comfortable posting there, until recently when things have started picking up with a lot of good interesting articles. So, most of the actual discussion got pushed to the weekly open threads, or off the site entirely.

One way around this would be to have 2 "circles" as you call them. Users tag their own comments and submissions as either "cannon" or "non-cannon", based on epistemic status, whether they've thought about it for at least 5 min, whether it's informative or just social, whether they've read the Sequences yet or are a newbie, etc. You could, of course, add more circles for more granularity, but 2 is the minimum.

Either way, it's extremely important that the user's self-rating is visible, alongside the site's rating, so that people aren't socially punished for mediocre or low quality content if they made no claim to quality in the first place. This allows them to just toss ideas out there without having totally refined potential diamonds in the rough.

An interesting thing you could do with this, to discourage overconfidence and encourage the meek, would be to show the user their calibration curve. That is, if they routinely rank their own comments as outer circle quality, but others tend to vote them up to inner quality status, the system will visually show a corrected estimate of quality when they slide the bar on their own comment.

Maybe even autocorrect it, so that if someone tries to rate a comment with 1 star, but their average 1 star comment is voted to 3 stars, then the system will start it at 3 stars instead. Probably best to let people rate them themselves, though, since the social pressure of having to live up to the 3 star quality might cause undue stress, and lead to less engagement.

I agree with Viliam that there is a big difference between trying to be a narrow-domain Wikipedia ("commons of knowledge") and trying to be a discussion site.

However I have another concern: incentives. From a regular-user point of view this looks like a system in which a cabal of superusers runs the show and the point is to collect a set of sacred texts which the newcomers are expected to study diligently if they want to hang around. So, why would I want to contribute? I might come and take a look at these sacred texts, but playing in this sandbox is a different matter. Sure, the high priesthood will labour on the commentaries and the commentaries on the commentaries, but why would I want to spend time here and write useful things?

I dunno man. Like, the statement that a lot of the highest quality discussion takes place on closed mailing lists is suspect to me. I've been on a few closed mailing lists, and they tend to be wastelands, because all the talking is taking place on reddit.

The most convenient/casual platform 'wins', in terms of getting most user discussion.

How do you select (or deselect) the root set?

What do you mean by 'content never moves outward'?
