I never mention winners because there are none.
When you see the entries now, they are ordered randomly. In two weeks time, the list will be ordered by score.
The voting phase is just a way to surface the most interesting entries and have people discuss about them.
I could easily skip voting altogether (the option is there) and leave the jam unranked, but I feel it would be a net loss.
Sorting really helps! Most visitors don't want to trudge through random broken entries. And I think it's fun for participants to check around and compare them.
So just enjoy it if you want, and vote how you see fit. Keep in mind that most entries get no score at all, so even a low score will still increase visibility.
I will think how I can convey the message that voting is about curation but it seems a shame to remove it.
After all, I guess you wouldn't be here now if it wasn't for this extra bit of fun?
