For me, Google+ likely won't replace Facebook. I've been on it since they started giving out invites for beta-testing, and it's still lacking a few things for me.
But social media is a part of my gig, so it's yet another thing I have to conquer.
The GOOD thing is how it will keep everything in one place, and make things easier that way.
I dunno if you guys can see this, but it explains why it'll be handy, and NOT as a social media outlet.
