hahah well I don't think it is too outrageous or unexpected that Scottws hasn't heard of him. Aside from his short stories, he is best known for writing some fantastic comic book stories, so yea.
I am currently in the middle of fragile things, which is a fantastic collection of short stories.
As for Niel Gaiman not wishing to write vampire stories because of Twilight, well... I guess Twilight pushed it over the edge, but vampires lost their place in horror a long time ago.
