1. Knowledge can only be volunteered, it cannot be conscripted.Great principles to chew on (as Mary Abraham says). Not only for the legal profession, but for all companies!
2. We only know what we know when we need to know it.
3. In the context of real need few people will withhold their knowledge.
4. Everything is fragmented (also refer to this one).
5. Tolerated failure imprints learning better than success.
6. The way we know things is not the way we report we know things.
7. We always know more than we can say, and we always say more than we can write down.
With respect to 'number 4' I'd also like to point to another great post by Snowden on bottom-up, low-cost knowledge management, starting with setting up blogs.Wiki's could/should be the next step in Snowden's bottom-up, low-cost community-building approach! John Tropea of Library Clips tells us how, by answering the question how blogs relate to wiki's.
