Groupy App (Mango) - Stumps me, anyone else?

[MediaDavep]

Groupy looks promising. I really like the idea of grouping all my news apps, below one tile on the start screen. That is the promise yet I can not figure out how the app works. Some reviewers love it and must have figured out the pinning trick. Can some smarter user out there throw me a bone?

I was wondering if an app like this existed. I downloaded, and tried it, but I must not be any smarter than you.
