How to pick a thesis advisor? This sort of question is probably in bad taste for math.stackexchange, but is probably in high demand. (I tried to start a site on Area 51 to house questions like this, but my request was closed due to the existence of math.stackexchange.)
I am advising talented students about graduate school. I believe that the most important thing one must be sure to do is pick the right PhD thesis advisor.

Question: What is your best advice on picking a good thesis advisor. (For the sake of levity, feel free to answer an opposite question regarding how to pick a bad thesis advisor. Just be sure you are clear whether you are indicating how to pick a good or bad advisor!)
