Maximum PC: If you've been avoiding Google+ all this time because you heard it was a ghost town, perhaps it's time you give the social networking site a visit. Google+, while still not on the level of Facebook in terms of users and activity, has now surpassed Twitter in monthly active users, making it the planet's second busiest social networking site around, according to data collected by Global Web Index (GWI from here on out).
So in Reality with active Users its probably behind newmyspace already.
It's not like you can't use both though:)
