Well, we've had some threads to workshop ideas (1, 2). Results are variable - but that's okay. The main thing I would suggest is to keep brainstorming ideas.

(e.g. perhaps a new rationality blog that isn't LessWrong. Perhaps a hundred new rationality blogs that aren't LessWrong. I keep telling ciphergoth to start blogging the things he says so eloquently and concisely in person ... I posted today in my journal about a matter that's arguably of rationalist concern in a world of woo - and it's been getting great comments - so it doesn't even require surmounting the barrier of bothering to set up a whole new blog. Make rationalist-interest posts to your own blogs!)
