Blogging Businesses

ResourceShelf points out the Fortune 500 Business Blogging Wiki, a listing of Fortune 500 companies with blogs, meaning "active public blogs by company employees about the company and/or its products."

A complete listing of all Fortune 500 companies is present within the right navigation pane, while the main part of the page lists business blogs that meet the above criteria.

Future plans include, once the list is "in pretty good shape," to add share price data that will enable the creation of a Business Blogging Index.
