The Science of Truthiness
E IS mC(Square) writes "Researchers at Indiana University have just launched Truthy.indiana.edu, which they humbly declare 'a sophisticated new Twitter-based research tool that combines data mining, social network analysis and crowdsourcing to uncover deceptive tactics and misinformation leading up to the Nov. 2 elections.' According to their FAQ, they define 'truthy' thus: 'A truthy meme relies on deceptive tactics to represent misinformation as fact. The Truthy system uses Truthy to refer to activities such as political smear campaigns, astroturfing, and other social pollution."
Truthiness was not coined by him as it was already a valid, albeit obsolete, word. He just attached a new definition to it.
