I think that getting set up is fine if the girl who's doing the setting up is the type that you like, since her friends are likely to be like her. I had a girl offer to set me up with her friends, but the girl wasn't my type, so I turned down the offer. Plus, it was the girl doing the setting up that was actually interested in me, using the whole set-up thing as an excuse (though she'd never admit that, it was obvious).
