Google opened up Knol to everyone this week and I have a hunch this will be an important idea. Knol (unit of knowledge) is like Wikipedia but with some subtle differences. It will likely become an important player in the knowledge publishing space because ...

1. Google has great search technology, and no information has any value until it can be found.
2. It's an authenticated publishing model; like the scientific community, experts can peform checks and balances on other "experts".
3. The smaller or mode discrete a knowledge artifact is, the greater its value. Knol accomodates this idea.

Create an account and tie your business content into it and vice-versa. I suspect this will generate some interesting visibility benefits for your expertise.
