It's not about mass, its about early adopters and followers
Things like Facebook or Twitter or the iPhone get started thanks to early adopters, and succeed thanks to the envy of followers.
It is all about being in and fashionable.
If Google+ is adopted by geeks and other such fashion icons ;) , then it will become a success.
So many people around me bought an iPhone because they found it "great" before having any idea of what that "greatness" was - not much really IMHO.
Now, Google is beating Apple with Android in spite of coming last to the game.
They got the attention and the hype.
Also, let's not forget that Google has a much better ecosystem around Google+, with GMail, Apps, Android, etc.
Mmmmh, promise of another era of company lock-in.
Biting the hand that feeds IT
