I like mods for mods. When a mod gets big, people (and yourself) start to expect a certain level of design coherence. You can't really throw shit at the wall anymore, you have to refine what you've got. You got weird, but you have to stay there or else you'll break shit or turn people off. But submods, they can keep pushing it without those expectations. You got weird, and they can get weirder.
It's the only place you get to see wackass shit like this.
