Go here, and you are at a Google Finance page for a company. So what? Check out the lower right, where it says Blog Posts.
The first post is mine, where I listed this company (along with 99 others) on the hundred fastest growing companies in Washington State.
Do I know anything about Applied Precision, Inc? No. But because I am the only voice in the blogosphere (of late), I am the authority.
So get off your butt and start blogging, or someone like me, with no real understanding of what you do, will be considered the authority on your business.
