Fortune 500 Business Blog Index

In collaboration with Socialtext, Wired has created the Fortune 500 Business Blog Index, a wiki that tracks which of the Fortune 500 is blogging. They found that only 4% of the Fortune 500 are doing so.

Chris Anderson, Editor of Wired, says, over time, as the list gets more robust, they’ll add the share price performance back in and turn it into a Business Blogging Index so you can see if blogging is indeed correlated to company performance.

In addition to this list, there’s the Corporate Blog List and the CEO Blog List.
