Hi. I work at a company that does statistical analytics for insurance companies. I've been following SL4 topics ever since I was 12, when I Asked Jeeves about the meaning of life and got a reasonable answer. I used to be a regular in the #SL4 IRC channel, but very rarely posted to the mailing list. I'm even more of a lurker here.
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.
