I think that Google+ may have a chance. That said, building a business is not just about a simple CRUD application. There is a LOT more that goes into Facebook and its adaption. There is even more that went into its timing and filling a void that existed in the market. Zuch didn't have many engineers at first, he just found a void and filled it. I think that there is an opportunity with Circles for G+ to fill a new void, but will it be enough? All the research in the world can't tell you. Only time will tell.
