Now things are going to get really interesting! Google announced a shiny API which will allow developers to create collaborative apps for G+ Hangouts.

According to the Google+ Platform website, this API will enable developers to “build games where you can see everyone’s reactions or use your whole body to communicate, collaborate face-to-face-to-face in real-time, or connect with family and friends in new ways.”

I’m really excited about that. APIs have enabled developers to create innovative and really cool and epically useful tools for end users. I can only imagine the level of face-to-face interactivity that an API for Hangouts can form.

You even get a Hangout button to include on your website that automatically starts a Hangout using your app.
