Hi.
It's been quite a while since I posted here, so long that I initially couldn't remember my username. I rarely have much to add, and even though "I agree with this post" posts are, I think, slightly more accepted here than in some places, just agreeing doesn't by itself motivate me to say so most of the time.
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.
