Next to an in-person demo, social networking is arguably the most common way to learn about apps through unofficial sources. It's only natural, then, that Google streamline the whole process of sharing Android apps in Google+. Include a link to a release in the Google Play Store with a Google+ post and the page now generates a clickable title card that installs the app right after choosing a target device. While the gesture doesn't extend to +1 votes, it's more than enough to give Android fans an easy and trustworthy way of spreading love for a favorite app. Or, at least, some shameless self-promotion.
