Blogging vs Essay

In the book on page 15 there is a section called Topic-driven Blogs there is a statement made that I disagree with.  The writer stated "While many of these blogs are run by individuals, topic-driven blogs are also run collaboratively by a group of contributors".  In the blog i'm following, Pac-10 Blog on espn.com, Ted miller is the blogger and he is an employee of ESPN (his job writing that blog).  Although he is an employee of ESPN and he has some guidelines for it, I believe and feel through reading his blog posts that he runs it himself and not collaboratively.  I also talk about that in my essay how he is unique to other bloggers on espn.com and they all talk about their own topics and interests based of their are of expertise. So in my mind with that statement from Blogging I don't think it applies to the blog i'm following but it may with other topic-driven blogs.
