Matchmaking plugin to match user profiles together?

I wonder if there is some plugin that allows users to create a really simple profile, and match themselves with other users who has done the same?

I’m creating a website for Michael Jackson, and I would like people to create their own profiles. With an avatar, their msn-adress and facebook adress. Then I would like some custom parameters, like what their favourite song is, and favourite album. Also in what city they live and what age they are. Nothing more really.

The ideal thing would be the option of creating my own parameters. This plugin should be registration free. It’s not something I want to be complicated. I want anyone to be able to create a profile INSTANTLY. Without registering. Is there something like this?
