As senior technical officer for the Defense Intelligence Agency and chief of its requirements and research group, Lewis Shepherd has promoted and observed a remarkable transformation that’s occurring inside the U.S. intelligence community as analysts begin to embrace Web 2.0 practices. When we first met in March I jumped at the chance to quiz him about how Intellipedia, blogs, and related methods are taking root in the various agencies. In this week’s ITConversations podcast we replay that conversation.

The Intellipedia story is fairly well known, but in this podcast you’ll also hear about the viral adoption of blogging among analysts. It’s surprising in one way because as Lewis Shepherd points out, you wouldn’t expect a senior analyst who has built up a reputation as the reigning expert on some topic to be thrilled about having a junior analyst comment on — or edit! — the work. But on the other hand, he notes that this is essentially a scholarly community and the urge to publish, and to be cited, is strong. It’s a fascinating tale of culture change.

In addition to social software, we also discussed a range of initiatives in the realms of virtualization, service-oriented architecture, and the semantic Web.
