It looks like Google has added a new feature to the Play Store on devices that will recommend apps to users based on personalized criteria. In a new section, you can find apps that have been +1'd by your friends, apps that are popular in your area, and even apps that are "popular with similar users" based on some undisclosed criteria.

The feature mirrors a similar recommendation feature that's been live on the web version of the Play Store for at least a month now. Still, it's even handier on mobile. Also, you can flag an app as uninteresting to you by clicking on the little cross-out icon on the side. Presumably, Google will use this data to personalize results even further. So, does it show you any new apps you didn't know about before?

Thanks Debadatta, Kalpik, Eduardo, Archit, and SysOne!
