I want to make sure that I plug the One Page Dungeon contest for 2020. This contest has been going on for 10 years(!) and its one of the great game resources to come out of the blogosphere.
One page dungeons are cool, they are hip, they are super easy to adapt into your games. I've used so many of these for inspiration, even dropping some whole on top of my players. There is something about the format and level of detail that makes these so easily digestible and the competition makes the cream rise. The reviews are a good read as well.
