Also, I should note, though surely everyone knows (heh), I like mpreg, magical AUs, and cracked premises taken seriously.
And mashups. I like those, too.
*wanders off comtemplating the notion that mashup might just mean AU, but might also mean, like, individual character mashups. Remus Snape/Hermione Lovegood, for instance, in which greasy snarky Gryffindor werewolf and bookish bushy-haired oddball hunt Snorkacks the night after the full moon at Spinner's End with radishes*
