Read it twice, still can't figure out what it is to be doing and why I would want it.
I have a feeling this is another gimmick to go along with the ever so popular social networking scene ?
Sad that we can't even share this article on Google+ yet. Tom's should add it.
To all the others saying what a waste of space G+ is, cool, stick to FB.
This is pretty cool feature, it allows non-users of G+ (pretty much everyone) to see a hangout live via youtube, and I presume they don't even need a G+ account to do so.
