Is there too many game jams on itch.io (currently 33 on the list)?
What if itch.io could only have one jam starting per day, or a maximum of 5 game jams at any one time.
Game jam ideas could be submitted to the community and voted on, with the winning idea getting the game jam slot.
With a queuing mechanism old high voted game jams could drop into slots when there is a game jam idea drought.
