That's pretty much the route Facebook took so it just might work but I too remain sceptical after mentioning G+ to a few people over coffee, beer or at the university and having to explain what I'm even talking about every single time.

that doesn't relate to the way Facebook took off AT ALL. The only "similarity" is .edu email addresses - in Facebook's case, it worked as an incentive because it was an exclusive club. Plus, it was an entirely different beast back then (and the "social network world" changed dramatically too)...
