Hangouts, the versatile video chat that continues to be the standout feature of Google+, got a visual and functional update today. The primary video feed is now bigger and better emphasized.

Hangouts also now offer screen sharing between users, a feature available on Skype and Apple's iChat as well as more work-oriented collaboration platforms. This is a killer feature for Hangouts, making it even more useful as a tool for live collaboration.

Hangouts allow users to bring in Google Docs, and smartphone users can use mobile video chat to participate. The addition of screen sharing makes Hangouts a versatile, compelling, free way to conduct remote meetings. Google Apps customers can use Hangouts with their team as part of the package.
