Linkedin Company Search

In Readwriteweb: Linkedin has a new search capability that lets you look at how you are connected to companies.   A nice idea with some subtle capabilities.   Though as I understand it you have to have legitimate connections to people in that company to use it.  As they suggest,  this could be a way to gather statistics about how companies are shifting by type of company and roles.  Unclear if you can get at that data, but it would be a rich source of understanding changes in industry, providing they have a consistent taxonomy.
