Apparently AT&T has been getting a lot of flack in the blogosphere today because of a leaked memo. This will have profound effects on their online reputation. The memo suggested to employees that they should oppose net neutrality, and many bloggers are essentially accusing AT&T of astroturfing on the subject of net neutrality. They’ll need to figure out how to concentrate on un defamation for the next couple of weeks–because otherwise permanent harm will be done to their online reputation.

My favorite part of the article linked below is where the writer says that Google is not a search engine, it is a web reputation management system. There is certainly a great deal of truth to that statement, though Google is both. Oftentimes Google is used, by detractors, to ruin the reputation of a person, company, or product.

The United Kingdom is undergoing some soul-searching on the subject of internet defamation. Their laws regarding libel on the Internet date back to the 1840s, and are a tad outdated at this point. However, there is another defense against internet defamation other than the legal system–online reputation management.
