Business market, particularly the small business market, is where most of the action and the money will be in the future, not personal blogs.  Benefits of blogging technologies, such as ease of update, content syndication, moblogging, audblogging, fotologging, and social networking, will allow small business owners to explode into the web like never before and propell blogging into a day-to-day necessity for survival. 

For proper perspective, think about how little hole-in-the-wall stores so common in Asia might use blogging technologies to improve their business.  Then scale it up and expand across the globe across language boundaries.
