tumblr, which i don't check up on often because it's a time sink, and it sometimes gives me a sad

pinterest, which i don't check up on often because it's a time sink, and i don't like that everything on there is basically stolen shit

FB, which i only have for stalking classmates talking to a family member

twitter, which i use the most; i try to keep up on my timeline regularly, but i don't actually post anything myself
