"I think Google+ has a lot of real promise," Kerravala said. "I think Facebook is most at risk. If Google comes out with functionality that Facebook doesn't have, I can see people switching allegiances. People are pretty finicky."
And that has to be welcome news to Google, which has had its fair share of social networking failures.
It's starting to appear that Google actually does have the chops, and obviously the financial backing, to put out a social product sweet enough to lure people, who tend to be creatures of habit, to spend less time with their traditional network and cultivate a new one.
It's been clear that Google+ has an uphill climb against Facebook, and even Twitter, but now it looks like the social network has some real momentum behind it.
"I think Google+ is good for the industry," Kerravala said. "It will step up the competitive nature. A market of one isn't very good. Having Google+ and Facebook both in this market will definitely push each other for future superiority."
