I once had a recruiter warn me in advance that a particular technical interview would be tough. When I got there the interviewer told me that we would just skip the technical interview because he'd seen some of my information online. That's a one-off. It hasn't happened since, and he might have just been really tired. But anecdotally it shows that there is value in the footprint. It makes some interviewers realize that they don't need to ask you lots of trivia questions.
