I've read for a while now, because LW is interesting. But I recently had a little bit of one-on-one interaction with AnnaSalamon, lukeprog and Carl_Shulman, and they're also just great people to interact with personally.
It seems that at least some of the people here are just plain really great people (in addition to being interesting).
I've been surprised at just how easy it is to find people who know so much more than you (because they've been here longer) and doubly surprised because they are willing to interact with you one on one.
Recently I asked "What bothers you about Less Wrong?". It might be worth going back and checking out what people had to say, to see if there's something you can do to make Less Wrong more fun for everyone. (A few people made cool posts in response to complaints about lack of technical discussion, for instance.)
Let's hear the other side. What is cool about Less Wrong? What drew you in, what makes you stay, what makes you obsessively read every comment of every post? Is they're something we're doing right that we should be doing more? Bonus points for pointing out how we can make our awesome traits even more awesome, or how to make our awesomeness more obvious to outside folk who'd appreciate it. Whatever it is, add it to the comments.
