A new study about the early growth numbers for Google+ is outlined by Jeff Bertolucci in a recent post on PC World:

Can Google+ attract enough users in a year to become more popular in the US than either Twitter or LinkedIn? A new Bloomberg-YouGov survey says yes.

The online survey of 1,003 US adults interviewed from July 29 to August 2, 2011 suggests Google+ is following in Facebook’s footsteps.

“Google+ is tracing a path similar to Facebook’s initial growth – building excitement in a core group of early adopters. For Facebook, it was college students. For Google+, that path is young, educated, single men who are heavy internet users,” said Michael Nardis, head of YouGov Investment Products, in a statement.
