Sidetalk is a new way to chat with your friends on Google Hangouts, with the account you already have. Instead of a bunch of floating windows, Sidetalk tucks away neatly into the side of your screen. You can always see at a glance who's available to chat with, whether anybody is typing, and any new messages that come in. Sidetalk is all about staying out of your way and integrating chatter into your workflow rather than dominating it.
