Price Floyd, who was the Defense Department's first head of social media, is moving on next week. 

A fixture on Twitter at @pricefloyd, Floyd softened the Pentagon's approach to P.R. by encouraging its employees to use social media more freely.

He's also known for soliciting followers' opinions and starting discussions on a broader scale than was previously standard for the Pentagon.

Tweets like "Interesting story yesterday in Long War Journal on Taliban strategy. Thoughts?" and "Is Tom Ricks on target about the future of Iraq?" demonstrate Floyd's characteristic style and breadth of reading.

He'll start life post-Pentagon by teaching a class on public diplomacy at George Washington University and consulting for the Center for a New American Security, where he had worked previously.
