I would have totally tried to get my family on board with G+ (I pitched the hell out of the circles thing to them), but I couldn't even make my own account as a Google apps user. Google hyped it super well, but they prevented the "super users", if you will, from evangelizing to their friends and family by not letting Google Apps users on board. The hype faded, and I haven't heard of G+ in normal conversation in quite a while.
