Looking through most of the questions here, a lot of the questions are theoretical. That should be allowed, but theoretical problems can be quite tedious to answer, especially since academic gamification is still very new. These theoretical problems shouldn't form the core of the site.
Perhaps a better option would be to make the backbone of the site similar to Stack Overflow. Unfortunately, these kinds of problems are difficult to describe in only question form. If you look at Stack Overflow, none of the problems are visible from their titles.
There should be less questions on how gamification works, and more questions like "I tried gamifying this thing and people reacted the wrong way. Please advise." or "This thing is boring. How do I make it not boring?"
