In 2004, the major political conventions gave a few dozen bloggers press credentials, a historic moment for the new media outsiders. And this year, the political conventions have tried to be even more open to bloggers, video reporters, podcasters and new media. The Democratic convention credentialed 120 bloggers, and the GOP has credentialed 200 bloggers, according to Forbes.

And the Democratic convention taking place in Denver this week also includes the Big Tent, a hangout for new media types outside the convention sponsored by Google and Digg. There have been panel discussions, appearances by political dignitaries and free beer, smoothies and massages there. (Simon Owens looked at the Big Tent in-depth for MediaShift last week.)
But perhaps the more interesting trend at the conventions this year is that it’s more difficult to tell the independent bloggers from the mainstream media bloggers. As traditional media embraces a multi-platform approach, including their audience in citizen media reports, the distinction between who deserves a media credential and who doesn’t has blurred like never before.
One example: Social-news site Digg and CNN’s citizen media-generated iReport are co-producing Digg Dialogg, where Digg’ers and other concerned citizens can ask questions to House Speaker Nancy Pelosi. The questions are then rated “thumbs up” or “thumbs down,” with the most popular being asked to Pelosi in a special Q&A with Digg CEO Jay Adelson. (No. 1 question so far: “Please describe what Net Neutrality is and your position on the issue.”)
