A cool anime bracket website I found: http://animebracket.com/
Hugely popular best girl contest going on in /r/anime: http://animebracket.com/vote/best-girl-contest-2-22-the-salt-will-not-stop-coming-/
One I made because I'm a hater: http://animebracket.com/nominate/worst-community/
These are more fun than polls on Batoto.
Hmm... maybe I should move this to games....
