That's just it though. G+ did most of what was listed here without the annoying app/game requests and a better interface. They had cross-platform text and video chat long before Facebook did either.

Most people won't bother switching platforms and in order for any competitor (G+ or otherwise) to take off is for everyone voluntarily migrate over.
