Without being on campus and making friends / contacts with these people how is the brand useful? "Oh man that looks like dilhead3112 from my M&A, I thought e worked here and that is definitely their green poomoji face, we should go talk to him! Probbably saved this company!" But seriously if their brand is networking, having a tight well filtered network I think would be a lot better for them. And if no one meets in person isn't that also bad for their brand? Everyone essentially becomes 2nd contacts (via harvard) on linked in.
