Hi. Like others have said, I tend to not post because I feel I can't add anything constructive to the discussion.
I don't think there's anything wrong with that though. A good part of learning can be knowing when to be silent and listen to what others have to say.
Hi.
And agreed.
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.
