As I recently wrote, I uploaded "Suzuki Twinkle" to the Android Market. What I was disappointed to learn was that there is no "Educational" category, either as an App or a Game. I ended up selecting Application --> Reference, for lack of a better category.
Suzuki Twinkle is an educational program. While I am sure there may be plenty who may argue for their on specialized category, I hardly think that having an "Educational" category would be considered specialized.
Google - Please fix this and add an "Educational" category to the Market.
