It's just been brought to our attention that Google+ has rolled out a new feature that integrates Google Play links directly into stream posts. Now when you link to an app in the Play Store, other users viewing the post can directly install it on their devices without having to be redirected to the Play Store listing first.
This is a pretty sweet feature considering how expansive the Android Google+ community is. Anything that helps users share apps between each other is good for everyone. Not to mention that this shows off the great potential and versatility that Google is trying to implement with all of its products and services.
