The G+ look and feel is way better than FB, IMO. I find FB claustrophobic and almost anxiety-inducing.
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..
