This afternoon on All Things Considered, I heard a piece on Open Source Intelligence, a project at New Mexico State University. The idea is to use publicly available information and student "analysts" to create meaningful intelligence information. I got to thinking as I heard the piece that in many ways, that's the power of blogging. People use publicly available information and critical thinking to produce useful aggregations of information from sources that interest them. Some of that is better quality and more useful than others, but the idea is there.
