Long time lurker here. Seattle WA. I've been following what Eliezer has had to say since 2003. Started way back on extropy-chat mailing list and reading SL4 archives, read Overcoming Bias since around 2008, and now I read here. I only lurk because I find that getting involved in discussion is too interesting, it distracts me from my projects.
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.
