a professional social networking website. i never ever use it except when i change jobs or a recruiter messages me going "HEY WE HAVE A GREAT OPPORTUNITY DOING *what i do* AS A CONTRACTOR"... but i'm permanent "OH WELL THIS IS STILL GOOD FOR YOU!!!!!1". i'm not putting any details of the new position there until it's all official and i'm moved, but i think its safe to delete my college job at this point.
