Google+ adds What's hot, +1 IDs to mobile apps
Google has just detailed two new features for its mobile Google+ apps and the web interface. The first is called the What's Hot stream, and allows users to quickly see the most popular content shared on the network by selecting the shortcut. It's located between the Circles and Nearby shortcuts.
The other addition involves the ability to view who shared a post by clicking the link beside the +1 icon. A list of all the Google+ users who shared the post then appears.
Google hasn't revealed when these features will be added to the existing Android, iOS and web apps, though it's expected to be very soon.
