Funny, because I dont know anyone who use G+ at all. Except these who was forced to make G+ profile while was registering just for e-mail.

And same time I know hundreds who use skype on daily basic on literally every device they own. Including TV. Only device in my house lacking skype it's refrigerator.

You dont need to use G+ to use Hangouts. If you have a gmail account you're a one step install away from using video chat. Doesn't matter if you have multiple gmail accounts or not, you just need a link, which hangouts gives you in the invite modal.
