> Hangouts are the killer app of Google+. Very much so. My brother and I live in different countries in Europe and the other day, we were able to have a video conversation (through a Google Hangout) with both our phones over cellular network (I was taking a walk in a park). I'm a tech person but even I was floored this was even possible.
