"A lot of academic exchange is about reputation, and the more visible you are, the higher your reputation is, and the higher your reputation is, the easier it gets for you to get grant money. When I become the Head of the department, I will launch a concerted effort to get other people to join Academia.edu because I really believe in the site. If we could all join and upload all of our papers from our department, then it would definitely increase our visibility as a department, and Im sure that will make a difference."
