This is probably an unpopular opinion but I've always thought a meme with some sort of loose continuity would be nice. Something like the dressing rooms of old. You have a general world set up that is up each month in the same universe, there's no obligation to tag but you can check in once in a while and tag as though you're just continuing another day there.

I considered doing this before but it felt like it was hard to integrate in bs culture, but I guess I can always just make a comm and link a new post monthly and see where that goes.
