Came across this pic on All Things D.

Just 2 days ago when I decided to try out Google+ I got the message that it was under testing with limited invites. And then in about 20 mins I got an invite and went ahead to invite most of my contacts and today it looks like all the techie people I know are already on Google+ adding me to their circles, uploading their albums and what have you. So much for a shortage of invites. :)
