A monthly thread for posting any interesting rationality-related quotes you've seen recently on the Internet, or had stored in your quotesfile for ages.
Please post all quotes separately (so that they can be voted up (or down) separately) unless they are strongly related/ordered.
Do not quote yourself.
Do not quote comments/posts on LW/OB - if we do this, there should be a separate thread for it.
No more than 5 quotes per person per monthly thread, please.
