This would have to be an order of magnitude easier (in terms of use) or feature-filled for most people to even consider switching. It would have to make it dead simple to import content (photos, posts, etc) from G+, FB, whatever. Even then, it will not last unless there are a huge number of people using it… and if there are huge number of people using it, that means that users need to pay for it or accept advertising… unless it is somehow distributed, a la BitTorrent, although I suspect that most people wouldn’t go in for that.
It’s tough to beat FB because everyone’s on it. If you want to remain in touch with everyone you’re in touch with on FB, then they all need to make the switch… and that’s a big, big ask.
I know a lot of people use FB to kill time but I actually use it to keep in touch with friends and family on the other side of the planet. So I take some bad with the good.
