I agree with Gunnar_Zarncke; the purpose of this thread seems well enough covered by Rationality Quotes + Media Thread. Still, no major harm done.
I would expect most people reading this already to be familar with @aristosophy (who appears to have stopped posting some time back, but there's a lot of hilarity worth mining). I think I saw another similarly-flavoured but still active twitter feed recently, but my stupid ape brain is refusing to remind me what.
Rationality Twitter is fun. Twitter's format can promote good insight porn/humor density. It might be worth capturing and voting on some of the good tweets here, because they're easy to miss and can end up seemingly buried forever. I mean for this to have a somewhat wider scope than the quotes thread. If you liked a tweet a lot for any reason this is the place for it.
