The biggest problem I have with this is that it attaches you to your friend's profile and whatever he does online. So, for example, what if a buddy of mine posts that he just smoked a joint, and then he endorses me for a job. Unfortunately most employers will likely draw certain conclusions from that, "He hangs out with those kinds of people? I'm not hiring him." It could be much subtler, like your friend posts "I love Bob Marley."
