Today, Google announced a new look for the Google+ stream. Gone is the weird, bubbly look that we've had for forever. The cards-centric UI that we've seen on phones and tablets is now coming to the desktop as well. You can select a one, two, or three-column layout and each individual card can flip over with a slick animation and provide more information and options.
Google's also improving its search and tagging functionality. Now, the service will analyze tags that you've provided and G+ will provide related hashtags to improve discovery. Even when you don't provide tags, Google can infer them.
