Hi. I've been following Eliezer's stuff since CaTAI. Been a lurker on extropy-chat, SL4, OB and LW. I remember once participating in an #sl4 chat, and being unable to post due to my accelerating heartrate.
Lurking can be debilitating. Well, symptom rather than the disease I guess.
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.
