The Google+ Android app is about to get an update which, among other things, now includes the What's Hot section. What's Hot is a useful portion of the web version in that you can see some of the most popular posts and stories floating around Google+. Now with it translated to mobile, you can access the content on-the-go right from your Android device.
In addition to What's Hot, you can now see who has +1'd your posts.
The update will be rolling out gradually so if you don't see it yet, sit tight. If you don't have the app yet, we've got links after the break.
