Corporate Blogging: 21st Century Transparency?

Blogs have become old hat.  They have gone beyond mainstream.  And yet, I am still amazed at the number of corporations that have them, often with higher-ups writing posts.  Is this what transparency and corporate governance has come to?  

Here are some notable blogs that could be of assistance to those interested in CSR, SRI, and ethical investing in general (aka readers of The Panelist):
