At Luke Muehlhauser's request, I wrote a script to scrape all of Robin Hanson's posts to Overcoming Bias into an e-book; here's a first beta release. Please comment here with any problems—posts in the wrong order, broken links, bad formatting, missing posts. Thanks!
The /domain/ use of Reddit is not something I'd ever heard of before. It seems like a very nice tool, and I'm glad you've shared it.
