PublicGyan, The Public Knowledge Exchange is the futures prediction market in everything. You can get the odds of say, an Indian winning a Formula One race. Its sort of like what Google is doing inside their firewall. This is part of the whole trend of “social intelligence.” The community members are not putting much credence in AOL being bought by Microsoft. When does US pull out of Iraq? They have plugins for Moveable Type, and WordPress plugin is coming. The exchange is the brain child of Srijith, a PhD student at Vrije Universiteit , Amsterdam and blogger Nitin.
