Somewhat snarky but very apt description of Mira Grant's Feed. I want to find it again. [more inside]
prinado and The White Hat get named as experts in a Grantland.com article, "Do Zombies Poop? An Investigation."
This is a great question but it didn't include the obligatory "For the purposes of a work of fiction..." disclaimer to keep it from being deleted as hypothetical filter.
Why did the "what would the scientific name for zombies?" question on AskMe disappear yesterday?
