"Google Plus went from ranking 54th in Hitwise's Social Networking and Forums category to ranking 8th in just one week," remarks ReadWriteWeb. "That's not all the traffic, either." No, the stats don't include mobile users or visits from "the ubiquitous black Google toolbar," according to ReadWriteWeb.
By Paul Allen's estimates, Google Plus currently has about 43 million users -- but no one knows how many of those users have ditched Facebook, if any. The Hitwise data does show that Google Plus has a surplus of "influencers" and "early adopters," which -- were the service not so new -- could be seen as a lack of traction with average users, i.e., most users.
