History of blogging

I'm willing to consider the "blog" as a phenomenon of recent history worthy of historical analysis, and here's someone who's trying. But most of the reflections seem entirely unrelated to what interests me about the potential of weblogs. This blog, I hope, stands among those that are not much influenced by how "A-listers," the MSM, and Huffington Post are changing blogging, and the declaration that "most bloggers spend three to five hours a day blogging" leaves me slack-jawed. The only observation that echoes here is #2, about the future being with "niche" blogging, and most of the other points seem to ignore that rule.
