PMOG stands for Passively Multiplayer Online Game.
It is a very intersting idea. PMOG makes the Web a play field of an MMOG. The
concept sounds like WebWars, the browsergame based on the EVE Online universe.
I can't tell better in my own words, so I let this
"PMOG transforms the existing topography of the internet into a game world for
players to vandalize, annotate, and curate. Players experience PMOG through a
Head-Up Display overlay in the Firefox web browser. This HUD interface allows
players to play with each other through the world wide web, creating information
quests, laying mines and building defenses around web sites. Order or chaos,
destructive or productive - players choose their alignment by the way they surf
and the way they use the tools of PMOG."
From the PMOG about page:
"PMOG is an infinite game built on individual network histories, transforming
our web surfing into ongoing social play. With a game head-up display in
Firefox, players can bomb each other, wage war over web sites, and lead other
users on web missions. Ordinary web sites become caches for items and currency.
PMOG fuses an MMO into our WWW."
