A post at Planet Algol asked: does the OSR need an adventure path? It's not a bad idea, if—as migellito suggested—we use Telecanter's idea of an island hopping campaign:
what if there were one page island and people wrote a bunch of them. Then you might have a campaign that you could pick and choose from a variety of isles.
A bunch of us recently posted one hour dungeon maps. Will anyone join me in jump starting the island hopping "Sea of Os'r" project with a 3-hour islet? (See the Wikipedia islet page for some inspiration.)
UPDATE: I finished my first islet, Isle of the Oxuders.
UPDATE 2: Lands of Ara is hosting the Sea of Os'r Adventure Path page. Check it out!
