The "Google doodle" today is actually a huge blue arrow pointing users to the company's Google+ social network, which Google opened to the public Tuesday after a three-month field trial.
"You're invited to join Google+," a pop-up message reads when you hover over the arrow.
Opening Google+ to the public is actually the 100th change the search giant has made to its social network in the last 90 days. Yesterday, Google also unveiled some updates to its Hangouts video chat feature and announced plans to incorporate search into Google+. But the service's Huddle chat service also has a new name: the more obvious "Messenger." To activate, touch the Messenger icon on the Google+ app home screen or the Messenger shortcut icon.
To demonstrate the changes to Hangouts, meanwhile, which include mobile support, the incorporation of more Google features, and a broadcast option, Google will host a live Google+ hangout with will.i.am tonight at 9pm Eastern. To access, the Google.com homepage also features a link.
For those who are just joining Google+, meanwhile, Google has put together a video (below) that explains that service and how it works.
