Your app can and should be ranked against other apps that are more fully featured and usable. If you aren't on the upper side of the curve quit spending time complaining about it and spend some more time learning and using that to code your app to be better.
Perhaps you're not a mobile developer. Mobile apps are about focused user experiences. Tight features that make sense within the context of the app. You wouldn't drop a crossword puzzle into an RSS reader app (even though newspapers have crossword puzzles... yes I had a user suggest this for my iPad newspaper app).
When users suggest a feature that should be there and it's not, that's fantastic, that's a totally different thing. I'm talking about unrelated, ridiculous requests that make no sense, or they make sense to 1 person in the entire world: the reviewer.
Just because an app receives some low ratings it doesn't necessarily mean it's a bad app or the developer is an idiot. Sometimes users leave bad ratings just because they can.
