Google Hangout

Are you a novice like me who wonders what "g+1" and Google+" and Google+Hangout" mean?

I have been reading a few articles both in ReadWriteWeb and other locations, and the more I read, the more questions I have.

As I understand from the Google+site, Google+Hangout allows you to:

• video chat face-to-face with your family/friends
• broadcast the dialogue to a more global audience
• host virtual meetings

You may sign up to "hang out" or for an app.

The question I propose here is: have you registered and if so, can you give me your thoughts on this new tool?
