Inoreader has plenty of advanced features. It's better than what Google Reader was like.

+1 to inoreader, I've been using it since the demise of Google Reader. Stable, full-featured, and great mobile apps.

I used to use Digg and switched over recently to Inoreader, way better in almost every way.

This looks great, thanks for the tip!
