Just how many could Google get to try their social interactive app called Google plus? Who knows? But one thing for sure, android OS lovers will likely support and install it in their android devices. Currently Google plus is in test mode which aims to bring Circles, Sparks, Huddle, Hangouts. Circles is similar to social grouping in Facebook but every relationship differs in some aspect, so to speak, degree of closeness e.g. Family members, best friends, lover/s, etc.The interface lets you add friends into circle just by dragging and dropping. It is Google's better-way of sharing since you already have groupings in Circle unlike in Facebook where you have to choose the persons whom you don't want something to share with.
