Can't devote 30 hours a week to World of Warcraft? Try racking up experience points and slaying enemies in the course of your mundane daily browsing instead. That's the thinking behind PMOGs - passively multiplayer online games. Blogfather Justin Hall came up with the concept as part of his master's thesis. Downloaded as a browser plug-in, a PMOG adds an extra layer of data and interactivity to the sites you visit. "We're giving people tools to wage information and routing war online," Hall says. "A framework for them to battle and bury treasure on Web pages." Does planting booby traps or tackling missions on Web pages sound like the exact opposite of fun? Think of all those Facebookers happily trading SuperPokes. Wired asked Hall to describe a potential PMOG experience.
