Googling your name shows a lot of relevant online presence: do you look less professional?
ScottWhigham: So Stackoverflow is a relevant community now? Huh....Anyway, I suppose it depends on the type of job you're after. Want a position in the FBI as a spy? Probably not gonna happen if you're a twitter junkie, I'd guess. Want a job as a web developer? Probably more likely to happen if the employer thinks you have your "finger on the pulse".I think that, as long as you don't have stupid things on the web that make you look unprofessional, you're okay.
