Taking few ideas from above and runing with them.

the blurbs instead of being campaign specific or encounters could be area features that are genre nuetral.

The easy way to do this would be 2 maps one plain and one with "Blurbs" or numbering and a cheat sheat for those that want them for a game.

This I believe can facilitate the original idea of this post the integraty of this sight being about maps and the want for generic areas not specific to the game.

If you keep them smallish with like a room or area cap this means you could make them quick 2 week chalenges

I still agree that the big chalenge would be better suited to being longer than any of the light or quick chalenges but again thats an opinion.
