I am a big fan of the Twin Cities New Media Alliance and its newswire site the Twin Cities Daily Planet. Their slogan is "Local News for Global Citizens" and they fulfill this mission by providing a mix of content from over 40 local media partners, citizen journalists, and a wonderful professional staff. They are making exceptional use of the potential of "Web 2.0" interactive capacity to foster participatory citizen journalism:
The Twin Cities Daily Planet is conceived as an experiment in participatory journalism, built on a partnership between professional journalists and individual citizens. Collectively, the residents of the Twin Cities have far more expertise and insight than can be found in any one newsroom. The premise of the TC Daily Planet is that new technologies are making it possible for these citizens to become more active and powerful participants in the news production process. One goal of the Daily Planet is to harness that community intelligence and enable individuals to share information and work together for the common good.
The roster of folks participating in this national conference is amazing. I'm especially excited by the large presence of young people among them.
