Greyhawk began the blog The Mudville Gazette in March, 2003, and the MilBlogs Ring - the first "community" of military bloggers - later that year. He has blogged from Iraq in 2004-2005, and again in 2007. In 2006 he started MilBlogs, a multi-author blog/chat forum for milbloggers. In 2008 he created MilBlogs TV, launching the milblogs 'brand' into yet another new media frontier.

The Mudville Gazette has experienced steady growth since it's founding in 2003. Mudville has been mentioned on Fox News, USA Today, MSNBC, WaPo and CNN, as well as in a cover story in Army Times.

Though fellow military members (from young people considering a military career to veterans of America's past wars) are probably more frequent visitors to Mudville, the site is more popular among civilians looking for insight into the military or reports from the frontlines of the war on terror they cannot find in the MSM.
