Google has introduced a new central location for Hangouts on the web. The new site presents you with all of your Google contacts, and options for getting in contact with them. You can easily initiate a video or phone call, as well as a new message thread by clicking one of the three big new buttons for that purpose.
From Hangouts engineer Jordanna Chord:
We are launching another way to use Hangouts today. From our new site you'll be able to take advantage of the best of Hangouts in the browser, along with an inspiring image to get you through the day. Check it out and let us know what you think.
You can also quickly access your contact, text conversations, and stored phone numbers by choosing from the readily-available side menu. Opening up the expanded menu will offer links to the Hangouts apps for both Android and iOS, as well as the Chrome app and Hangouts Dialer app for Android.
The new Hangouts experience is rolling out right now.
