I created a 2011 update to last year's Best of Rationality Quotes collection. (Here is the original.)

Best of Rationality Quotes 2011 (360kB page, 352 quotes)

and Best of Rationality Quotes 2009-2011 (700kB page, 706 quotes)

The page was built by a short script (source code here) from all the LW Rationality Quotes threads so far. (We had such a thread each month since April 2009.) The script collects all comments with karma score 10 or more, and sorts them by score. Replies are not collected, only top-level comments.

A year ago commenters asked for various statistics and top-lists based on the data. This year I re-ran the scripts I wrote to answer those requests. (Source code for these is also at the above link, see the README.) I added the results as comments to this post:

Top quote contributors by total karma score collected
Top quote contributors by karma score collected in 2011
Top quote contributors by statistical significance level (See this comment for a description of this metric.)
Top original authors by number of quotes
Top original authors by total karma score collected
