This entire notion of a professional social network I believe is flawed in that it is built upon the notion that it would be better to hire someone who has a smaller degree of separation from you, which makes no sense. I do a fair amount of interviewing of programmers, and not a single person I work with could give a damn about anyone&#x27;s linkedin profile; it&#x27;s meaningless. I just find the whole idea to be very shallow, vein, and obtrusive.
