Basically there are two types of blogs. Firstly would be the internal blog which are accessed through the corporation's Intranet and is a weblog that any employee can view. Internal blogs may be used in meetings and e-mail discussions that are useful when the people involved are in different locations or have conflicting schedules. Blogs may also allow individuals who otherwise would not have been aware of or invited to participate in a discussion to contribute their expertise.
Another blog would be the external blog which are publicly available weblog where company employees, teams or spokespersons share their views. It is often used to announce new products and services, explain and clarify policies or to react on public criticism on certain issues. Certain corporate blogs have a very high number of subscribers. The official Google Blog is currently in the Technorati top 50 listing among all blogs worldwide. External corporate blogs, by their very nature are biased, though they can also offer a more honest and direct view than traditional communication channels. Nevertheless, they remain public relations tools.
