Hi.
I guess I have some abstract notion of wanting to contribute, but tend not to speak up when I don't have anything particularly interesting to say. Maybe at some point I will think I have something interesting to say. In the meantime, I've enjoyed lurking thus far and at least believe I've learned a lot, so that's cool.
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.
