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.

Hiya! Everywhere I go I primarily lurk, the reason being that commenting just takes way too much time for me. I find it very difficult to put my thoughts into words, and I constantly obsess over small details. As a result, even a simple comment like this can take up to 15 minutes to write.
I obsess over small details... after submitting the comment. Hence I will often edit the same comment half a dozen times. (I love sites where I can't edit my own comments!)
