Look Up?

If you are in a job that involves the perusal of applications -- such as applications for graduate admission, for postdocs, for faculty positions etc. -- do you use Google (or similar) to try to find out more about applicants in whom you have a particular interest?

For example, if you are a professor who advises graduate students, do you Google (or whatever) some or all of the applicants who mention an interest in working with you? If you are on a search committee, do you Google (or whatever) applicants, or, at least, those on the short list? And so on.

I have never done this, but I know that some people do it routinely. So I wonder: Does such searching ever turn up information that is relevant to the decision-making process?

This same question can of course be turned around to ask applicants if they have Googled potential advisors etc. as part of their decision-making process about their education and careers. In fact, I have encouraged something similar in a post a few months ago: that prospective graduate students should look up our advising records, publication records, grant records etc. In that case, however, I was proposing using citation databases, department webpages etc. That's a bit different from encouraging a broader search, although I have nothing against such searching; I just wonder if it is useful.

Hence my question to readers today: Has anyone found out anything via a Google-like search that influenced a decision about an applicant (or potential advisor, colleague etc.), for or against? Can you give examples? Can anyone explain why it might be good to do these searches on a routine basis, other than just out of curiosity to see what someone's time was in a 10k fun-run or to see a photo of someone amidst a drunken revel in college?
