I love all of these! It's like one of those little taster things, where instead of sampling wine or chocolate or cheese you get different flavors of AU. *_*

The ones I find cliffhangeriest (as in oooh shiny [/spends ten minutes imagining backstory/what happens next]) are the Meenska and the Humans-Invade ones, although the closet-Karkat, FFstuck, mermaid, space pirates, and Jadewolf ones come pretty close. (Okay it's mostly the Humans-Invade one at the top of the list, I just find the idea of a Meenah-Vriska partnership too awesomely horrifying to pass up.)
