I agree with you Hailley. Most marketers are not sure about the potential of G+. The only saving grace is that it's backed by Google Inc., which at any point in time can pump in billions to make it a lot more competitive. I think every social media channel needs to solve a consumer need, something that Facebook, Twitter and Instagram do.
In some of the SMX conferences last year, representatives from Google have stated that G+ is the future of Google. However, I see G+ to be more of a data warehouse. G+ has all your information right from where you're located, your search history, your demographics, your emails, your phone notifcations, etc. I think Google might open itself up to selling some of that data to brands in the future - when privacy won't be a concern.
