Over the past weekend a game of virtual tag broke out on Twitter under the hashtag #TvsZ. Twitter vs. Zombies was, in the words of the game's organizers Jesse Stommel and Pete Rorabaugh: "an epic zombiefied experiment in Twitter literacy, gamification, collaboration, and emergent learning. Part flash-mob. Part Hunger-Games. Part Twitter-pocalypse. Part digital feeding frenzy. Part micro-MOOC. Part giant game of Twitter tag."
