With the creation of Google’s answer to Facebook, Google+, we can see that people are hungrier than ever to be socially connected online. Google+ has quickly become the fastest growing social network, with 13 percent of US adults already signed up since its launch a mere two months ago, at the beginning of July. In terms of future growth, if the calculations are correct, they will hit 22 percent by the end of the year, putting them ahead of both Twitter and LinkedIn, which have been around a lot longer.
