Google+ is hot, hot, hot. The social network has pulled in 20 million unique visitors in a mere three weeks. Leading the way is the US with 5 million and India with 2.8 million uniques.
It'll be interesting to see if Google can expand the service fast enough to keep up this momentum. I like chatting it up in 140 characters or more and Google+ is just so light, fresh and fun. It's like Happy Hour all day long.
