Tagentially related: I have actually been planning on putting some clarifying information on any future resumes that I send out indicating where my website is, where you can find some "jerf" postings, and which are not me. I don't even use Facebook and the last thing I need is to lose some job because some guy with my same name is out there making ethnic slurs or something on a Facebook page.

I'm actually surprised that we haven't seen a news story about that, perhaps because if it happens you'll never know that's why you didn't get the job. As more people come on the Internet, the odds of your name or handle being truly unique go down. The google results for "jerf" have gone from all me, all the time in 1999, to a random hodgepodge of results, mostly courtesy of user accounts on high-page-rank services I don't use that aren't me, oh, and oi for that Urban Dictionary result. (That one was news to me. I could have gone without knowing that one, even though I'm sure it's another of UB's crappy "some guy somewhere used this word once and I'm going to put it on UB" results.) And my real name's results have long since been cluttered by "not me", some of which are even close enough to me to be confusing to a potential employer due to technology interests.
