Now that the iOS App Store has become overloaded with software, it has become rather difficult to separate the wheat from the chaff so to speak. The problem is that for every awesome application released, there are one hundred other garbage titles for it to become buried under. This is why AppGrooves decided to release their new recommendation tool, meant to only show users the best that the App Store has to offer.
Applying the 'Hot or Not' model for rating items to applications looks to yield a constantly updating list of the best software available on the marketplace. Users can even link directly to a specific program's App Store page from within AppGrooves itself. If that isn't customer service, then I don't know what is.
Take an active role in letting others know what is amazing on iOS. User votes can truly make a difference. Give it a look, it might even save you a buck or two someday.
