I am mostly a lurker because 1. I don't really have much time to read through all the posts, and have even less time to actually post and 2. everyone's got their little groups that they are friends with and I am not a part of anyone's circle of friends. But I understand that it's my choice to post or not and to be a loner, but I don't think that it would really bother someone if I just lurked most of the time.
