Completely agree. It may too little too late for mass adoption. At the moment I see it as a better version of twitter, more for information sharing than for social interaction. At least that's how I'm using it. This could also depend on the fact that a majority of my network on G+ is made up of colleagues and other early adopters. I do really like the potential it has by linking to other very successful Google products I already use. Other than that, lots of ifs indeed.
