OK Cupid call themselves the best dating site on earth, and I don't know about that but I will say that they now have one of the best branded blogs evah. At first they were digging up rather mundane stats from the site and sharing it, but now they've found their groove and here is their graph-laden backed up by science fun post on the best pose, camera, and time of day you should take your profile photo: "Don't be ugly by accident".
I mean, their graph's prove that iPhone users have more sex. Give'em some love.
