eWeek has a great interview with John Patrick, ex VP of internet technology at IBM. He discusses enterprise weblogging and how it relates to KM. Patrick emphasises the difference between traditional top-down, centralised, failing approaches to KM and the bottom-up, emergent, empowered approach that blogging entails.

MIT researchers say that [blogging] represents a new genre of communication that offers people alternate filters to mainstream news of events

KM wasn’t overhyped – it was underdelivered. Blogs can potentially deliver the grassroots discussion and knowledge sharing that top-down corporate sponsored efforts never could.

There is a lot of good material in the interview – definitely required reading.
