We all have a purpose for being here, too. A lot of boards it's just ":D HEY! We're a bunch of people together!" so it evolves into a bunch of people together, including all the sh*t that goes with that. Most of are here to improve our knitting, share our trials and experiences, and to have some fun. So we are a bunch of fun knitters.
We're also a smaller community. The laws of probability say that if we ever get big enough, we'll start to get a few mean-spirited jerks.
