Google just dropped an update to its social networking app for mobile. Unlike some other apps, Google's brought a ton of new features that are actually useful. The Stream is now faster, doesn't immediately jump to the top of the feed when the app automatically refreshes, and shortens entries so you can see more of them at once.
A few other improvements have been made. A new What's Hot! section allows you to follow what everyone is talking about, in an obvious attempt to compete with Twitter's trending topics.
