"Could you please be just a little more specific joel as to what
constitutes a GOOD APP"
In general, I would say an app that is engaging to the user, is original, fun, and has replay value. More specifically, an app that is not simply listed to temporarily drive traffic to get a short burst of ad revenue by copying a pre-existing app and renaming it, or using and manipulating image icons of other games, or any other such techniques which drive up popularity but result in a poor user experience. Users quickly stop playing bad apps like these since the only purpose the app served was to ride the brief wave of recent popularity based on this listing criterion in order to provide a short term benefit to the developer. As a result, some developers will constantly push out low quality apps like this - using many of the aforementioned listing techniques - whose sole purpose is to drive this temporary traffic.
"Good" apps are apps that users will tell their frends about because they are engaging. Apps that don't provide this level of engagement, when given too much exposure, obviously hurt the site since they diminish the end user's overall experience and may drive the user away completely. This is why we have been working on new methods of app listings which will be more geared towards quality apps while still rewarding the small developers who are innovative.
A "Featured App" is the highest example of a "good app". Apps will be put in this section if our reviewers feel they are truly exceptional. If you have developed a quality and original game, you are welcome to ask email@example.com for consideration for the app to be displayed in the Featured Apps section.
