From the article intro: "While great examples of well-read traditional blog publications will probably be with us for some time, the real growth in the future of blogging will come as content producers turn the content production and consumption behavior that blogs accelerated into the ultimate tool for sales conversion.
So, you no longer need to think in terms of a blog as some extension of your website, but more in terms of blogging behavior and technology as the fundamental component of your content strategy.
Websites owners are using blog software to turn their sites into highly engaging content management systems and that evolution will continue to pick up steam for every type of business in the near future."
I agree: blogs as such are not the best channel anymore to deliver your best value proposition to your potential fans. You need something more focused and with greater content value.
