Also, Hangouts is G+ best feature but sadly it is really hard to get people together on it. Why when I invite someone do they not get an email or IM?? They only get notified within g+ itself and it isn't easy to find the invite. On recent jobs several times I've tried to get meetings together on g+ only to resort back to conference calls (!!? WTF??) every time because people couldn't get on the Hangout. That is a real shame.
