Corporate Blogging: Is It Worth the Hype?

While reading the article by Backbone dealing with corporate blogging, I found the results to the question, "How quickly did you see the results from your blog on the following factors..." very interesting. For the majority of the factors listed, the companies who had blogs saw results from the blog within the first week. This surprised me because I thought it would take much longer for the companies to see changes and reactions from the blogs then after just one week of participating in blogging. This really proved to me that corporate blogging can be very influential and effective if used correctly for organizations. What do you think about this?
