A discrete website for interesting yet random people, where you can express yourself without being judged. You can post whatever you like, whenever you like. Not everyone understands tumblr, so don't worry about idiots from school/work/anywhere to be joining.
Facebook person: I think I'll join tumblr.
Tumblr person: NOOOOOOOOOOOOOOOOOO!
