"Blogs, I believe, are much different than diaries, with which they are often compared. Their very setting attests to a social as well as a personal purpose. I believe they are about sharing and growing what we know and what we can tell.
I also believe they will succeed where "knowlegdege management" (and every other kind of management) has failed. It's the same reason online bazaars like eBay are succeeding where every business intermediary with a 2 in the middle of its acronym is struggling. They're about us. They organize themselves around whatever topic gets us going, for as long as the topic stays interesting. Then we ? whoever we are ? move on, keeping safe in the tacit what those who operate only in the explicit will never understand, much less "manage."
