As a huge Google Plus and Hangout fan, it was very cool to watch U.S. Vice President Joe Biden use a Hangout On Air (HOA) for a Fireside Chat (Jan 24, 2013). The hangout was on gun control and reducing gun violence. Another very cool surprise was to see Guy Kawasaki as one of the participants. Check it out; it’s worth watching, even if just to see Guy show off some communication skills.
G+ Hangouts seem to be taking hold all around the World and as Google continues to improve, I believe they will overtake Skype and become the number one video conference tool.
