There's a pretty decent discovery mechanism. The more you rate, the closer you are to the front page. It's not perfect, but I don't think I've gotten less than, say, 50 people rating my games (http://www.ludumdare.com/compo/author/mscottmcbee/ If you're interested).
Rate others, leave comments, and people will play your game.
