I've noticed that games that have had the most votes are those created for fremantle (I dont know in other categories), I suppose N900, perhaps I could have made my game to N900, for more people, because I suppose here there are more people who votes with a N900 than N9 or N950. These are just my opinion!!
Not unlikely, since everyone (once) interested in development for fremantle should have a maemo.org account (needed for the autobuilder). So a N9 owner had to create one at the beginning (!) of the Coding Competition solely to take part in the voting process 3 months later, while a N900 owner with a (long forgotten) maemo.org acoount was notified via e-mail at the beginning of the voting phase.
