Arianna Huffington is entering the world of citizen journalism with her announcement of a new project: The Wisdom of Crowds Hits the Campaign Trail. It's got the makings of a great effort: she's recruiting citizen journalists from around the country to cover the major presidential candidates and asking each of them to contribute to a candidate-specific group blog -- offering written updates, campaign tidbits, on-the-scene observations, photos, or original video. The goal is to provide more sources of information, and more outside-the-mainstream voices on the upcoming presidential campaign. She's got the readership to make it happen.
