I'm getting tired of people insisting that blogs are one thing but definitely cannot be another. Sure, I know exactly what Searls is talking about: the type of blog written by individuals (like, for example, this one). But that doesn't mean that General Motors is abusing the blogosphere by producting Fastlane, which targets the consumer audience of automotive enthusiasts.
I'll keep on saying it: Blogs are lightweight content-management systems, and as such, are applicable to any task the use of such a system accommodates. Consequently, we'll continue to see blogs branch out along several evolutionary paths. Some will be terrific, others will cause mass shrugging, and still others will be wretched.
