The Guardian ran a full page story yesterday about the growing power of blogs - in terms of influencing how businesses are run.
The main premise of the article - Companies wake up to blogs' barking by Andrew Clark is, "many firms have started to pay attention as a rapidly expanding slice of cyberspace is devoted to vitriolic, often obsessive blogs listing the shortcomings of well-known companies."
The main blogs that are mentioned are critiques of Apple, Wal-Mart and Asda, Dell, McDonalds, and, United Airlines.
Clark goes on to suggest, "mostly, the contents of such sites are anecdotal. But they can become a significant rallying point for a company's critics."
