The G+ UI is great if all of your other friends have Google accounts and have signed up for G+. Pretty sweet.

But for those that haven't signed up for G+ or even worse, don't have a Google account at all, forget about it. I wanted to set up a Hangout for my family members in other states to chat in, but after the catastrophe above, there's no way I am going to try and convey those instructions to others..
