Growth on Google+ has been great, over one billion items shared

Wondering why Google+ ran out of disk space? Looks like it might be a casualty of growth: in today'searnings call, Google CEO Larry Page revealed that since its launch, more than ten million people have joined Google+, sharing some one billion items every day. Those numbers not big enough for you? Then chew on this: that little +1 button? It gets clicked 2.3 billion times per day in its own right. It's still a far cry from the 750 million users actively addicted to Facebook, but still, that's a heck of a start.
