Google recently added a recommended for me section on their Chrome Web Store. They are now rolling out a similar feature on their Google Play Store on Android devices.
I am yet to get this update but Google would be showing apps and other content based on various parameters.
Users would get recommendations based on what apps they have installed, recommendations by people in their Google+ Circles and even based on where they are.
This is a good update from Google as the apps highlighted on various pages in Google Play Store usually remain static.
