DeviantArt - I don't use the site nor do I go there to laugh at people; I just enjoy seeing that other people use their imaginations in similar ways as I do, no matter how good or bad their actual artwork is.
Tumblr - I think it's fun to reblog images of my special interests.
GaiaOnline - Okay, yeah, I know I have talked a lot of smack about this site in the past, but the other day when my brother said that he joined, I was tempted to make a new account there, which I did. The allure of being rewarded with virtual points (by posting and playing games) which you can use to decorate your avatar is extremely addicting. My old point still stands that there are more jerks there than there are on WP, but as long as you don't say or do anything that's too out of left field (or mention the fact that you have AS for that matter), then no one will bother you.
