ratemyrack.com
A new site out there, along the lines of amihotornot.com, amigothornot.com, and amigeekornot.com. Basically, women send in pictures of their exposed breasts and the voting is based on that. You can sort "racks" by score, newest, submit a photo, or just the good old Rate-o-matic. This site also features discussion boards, and the all new Rack Chat. I guess this just takes amihotornot.com and gets right to the point. They don't kid around about content, they've even got one of those "This site features adult content" warning pages.
