These blogs are often created to appeal to the demographic that the company needs to court, and the content may have quite a lot to do with the activities of the corporation, or it may have very little to do with the company itself. Often, a corporate blog will focus on the kinds of content likely to attract the desired surfers, even if that content is not related to the product or service that the company provides.
Some bloggers feel that corporate blogging is a kind of validation for the blogging movement, and shows that this exciting new medium has really infiltrated the mainstream. Other bloggers consider the kind of viral marketing that corporate blogs practice to be unethical or distasteful. In any case, watching the evolution of corporate blogs and whether they survive and proliferate or fail and disappear promises to provide some interesting insight into today's consumers.
