This video does a great job of going through all of the new parts of Google+ hangouts such as how to edit Google Docs, diagrams and doodles together with others in the hangout. If you have not heard of "hangouts" it allows you to meet with up to nine other friends in a video chat. If you have a Google account, you have a Google+ account in which you can go into a hangout. It can be used to collaborate with colleagues in different locations. I found out about the video from a G+ post from Jason Mayes who is an engineer for Google.
