Eurekalert points to a story from the Office of Naval Research which discusses their interest in blogging for rapid technology and knowledge development:
"The blog is one of 12 pilot programs, selected for funding from a field of 120, for demonstration through the DoD Rapid Acquisition Incentive-Net Centricity (RAI-NC) initiative. The RAI-NC, managed by the office of the Pentagon’s chief information officer, aims to demonstrate processes to speed up the development of net-centric, “transformational” approaches to defense technology development and acquisition."
It appears they're using Traction Software's solution... bummer.
