It is true. I am indeed on Google Plus thanks to World of Warcraft friend Yvonne.
First impressions. This is what Facebook should be. Much easier to manage and categorize your friends using circles. And everything is not public! Plus a much cleaner and clutter free interface.
If you want an invite, send me your GMail email address and I will try to get an invite to you. The invite link is not always available. Not sure if they only turn it on at certain times? Or if I have a daily or weekly quota? Anyway, I will do my best to get you added if you are interested.
