I have no idea how I came upon this but I have been receiving a lot of invites and forward on LinkedIn, so this afternoon Ii was surfing around and there it was. The 44th President of the United States on LinkedIn!
I loved the gesture, I don't think he really needs the visibility nor do I think anyone will request a referral from him on LinkedIn, but I do like the approachability of the worlds most powerful leader on a site like LinkedIn! That says a lot about his marketing team, not wonder they were recognized for their excellence in pulling off a successful campaign.
