how will the results of the voting be announced? Will it be listed by language, overall, or no winner announced period?
I just realized there's nothing stating a winner will be announced for the jam anywhere on the main page so if this is about creativity, discovery and collaboration then I question why have the rating system in place at all?
I think Dominik raises a good point where rating anything other than 5 stars is already seen as anti-collaborative and bad. For example even if I feel the entry is not perfect/flawed in some way I absolutely do not want to rate it anything less than 5 stars cuz I risk just looking like a dick for it, even if my goal is to criticize the entry and point out flaws while also listing what I liked about it. Therefore I just end up leaving a comment anyway.
Perhaps for the next jam, just don't have rating at all! Encourage people to comment and leave their constructive feedback without any need to introduce any competitive element, cuz in this jam it was confusing how winners would be chosen - and if there would be winners at all :)
