How do you choose a good therapist?

So I’m looking for a therapist (and that’s the best way ever to start out a question on Yahoo!Answers), but I’ve already been to one who I just didn’t mesh with well at all. Is there some way I can find a good therapist without blindly picking names out of the yellow pages?

You could talk to someone you know who went to a therapist. If you trust that person’s opinion and like what you hear, it might be better than starting with a list of name from the phone book and hoping one pans out.
If it comes to it, you might talk to someone who knows someone, but obviously this way would be less reliable.
