Why Mythos Hoedown?

I should note why I decided to call this blog Mythos Hoedown: One of the first reviews I did for RPGnet was for a Call of Cthulhu supplement called At Your Door, which was not Chaosium's best work. It featured a scene where a bunch of Mythos monsters and cultists gather together in a stadium in a ruined city in California, have a party and mu-ha-ha about their plans for the world, which the investigators are meant to hose down with automatic gunfire. It struck me as silly and a little farfetched, and nicknamed it a Mythos Hoedown, which I later expanded to mean a situation in a scenario where multiple unrelated Mythos monsters occupy the same space without a good justification.

You can argue, mind you, that the Mythos doesn't follow human convention; but written scenarios do, and so to have, say, Sand Dwellers bumping elbows with Dark Young of Shub-Niggurath and Deep Ones feels incompatible with the suspension of disbelief.
