I'm not sure Google's invite only strategy is a particularly good idea. I was excited about both GMail and Google+ when they were both launched but by the time I found access to both of them I didn't care anymore. For GMail, my provider (and other competitors) increased the storage limits to compete. Google+ was obviously a dud by the time I found access to it which may not have been the case if they just let everyone in to begin with.
