I've been reading this blog for about half a year now and loving it after Accelerating Future (I think) referenced it for something. I don't post many comments because anything I'd have to contribute usually already is, but I find that if you surround (or read) more intelligent people, they have this peculiar way of making you the same. Keep going Less Wrong, a lot of us are learning all sorts of great things from you!
Some research says that lurkers make up over 90% of online groups. I suspect that Less Wrong has an even higher percentage of lurkers than other online communities.
Please post a comment in this thread saying "Hi." You can say more if you want, but just posting "Hi" is good for a guaranteed free point of karma.
