Visitors using personal computers spent an average of about three minutes a month on Google+ between September and January, versus six to seven hours on Facebook each month over the same period, according to comScore, which didn't have data on mobile usage.
WOW!!!: Google+ has some original features—including "Hangouts," which lets people start a video conference with up to 10 people
Facebook has 845 million monthly active users.
Google+ acts as an auxiliary to Google services—such as Gmail and YouTube—by adding a "personal" social-networking layer on top of them.
Last August, for instance, social-games company Zynga Inc. began offering its
games "CityVille" and "Zynga Poker" to people who use Google+. Zynga now has
46.8 million monthly active users of "CityVille" on Facebook and 33.2 million
for "Zynga Poker," according to tracking service AppData.com. But the growth of
its game players on Google+ has been slow, Zynga said, declining to reveal
underlying numbers.
