I use facebook's Paper app, which is essentially this. I have found it to be totally stable, a much more pleasing interface, and (for those who care, I personally don't) you don't need the Messenger app either. I don't use the content aggregation either--it's just a significantly nicer facebook interface.

It's rate 4+ on the app store, with 512 reviews. I think it's just less well-known.
