I really miss the social aspect of Google reader before they axed it back in 2011. It's not really social in the traditional sense, it's social in the sense that I could outsource the job of scouring feeds on various topics to other people. Everything they found interesting would be mainlined right into my reader interface so I didn't have to personally check 20 feeds on Android.

I do hope that Digg can create a simple and fast interface that captures this concept without too much clutter from the more traditional social features.
