The Democractic National Convention has credentialed a number of bloggers. Their access to the convention, the delegates and the activities will be essentially the same as the traditional media. Dan Gillmor has a good take on what this might mean:

Where Big Journalism remains mostly a lecture, blogging is more a conversation. The bloggers are individuals, moreover. Some are experienced political journalists. Many in Boston will be neophytes when it comes to national politics. All, however, speak with genuine voices from their blogs -- voices their readers have come to know and in many cases trust. Blogs are simultaneously immediate, intimate and subtle.

Due to the very nature of blogging, they'll be reporting from the edges of our increasingly ubiquitous data networks. I hope they'll experiment with the tools of this emerging trade. Technology has given average people new ways to collect and distribute information to global audiences, and this is an opportunity to show how grassroots journalism can be created and, crucially, seen in new ways.

There's a list of credentialed bloggers at CyberJournalist.net. And you can check out this aggregate feed for convention bloggers' posts as well.
