Welcome to Gaia Online
GigaOM » Move over MySpace, Gaia Online is here: "By the middle of last year, it was attracting half a million unique visitors monthly; fast forward to last month, and that number is two million. It’s not a traditional MMO like World of Warcraft; it’s not a social game like There; it doesn’t originate from Europe like Habbo Hotel or from Asia like Cyworld. You haven’t heard of it partly because the San Jose company has kept a low profile.
Another reason you’re still likely in the dark: it’s primarily designed for teens. But with online worlds all sizes and styles poised for an explosion, you’ll almost certainly hear a lot more about it soon."
