Cincinnati is hosting its own review of the phenomenon below within independent media. Independent Media Exposition 2003 will cover "DIY Publishing, Blogs, Webzines, Net Radio, Minority Voices in the media and much more." This event will be interesting as audience-created content is clearly at home at the independent, grassroots level.
Note: The IME mention above is a direct result of someone pitching this public relations blog. IME did their research and sent a targeted, low-pressure pitch to me via e-mail. The end result is a link back to their site, per their request.
