I have Google+.
However, I never ever ever use it. Some of my friends have it but I really don't see the point.
I'm on Facebook all the time and, while I don't like it too much, it is convenient to see and reach out to many people I know with it.
For the last year or so, I've had occasional "Do you want to use your real name?" on Youtube when I'd log on. I'd always say "No" and then they're like "Ok, we'll ask you again later!". NO FUCKER, DON'T ASK ME AGAIN, I DON'T WANT TO TIE MY ACCOUNTS TOGETHER YOU SONOFABITCH, if I wanted to tie them, I would've done so already.
