Commentary on top 10 blog usability mistakes - having a domain name owned by weblog service

Tenth and final mistake in the top 10 blog usability mistakes by Jakob Nielsen (2005) is having your blogs address pointing to blog service (Blogger, Typepad etc). Nielsen sees this as sign of naive beginner who shouldn't be taken too seriously. And again, in my opinion this mistake is not really usability mistake at all but rather a question about PR and image. If you are pro blogger by all means you can have your own domain and build your own blog as you like it, but I follow several professional blogs and v-logs (some in Blogger, some in other blog services), and the idea that blog service provider would somehow lessen the value or image of information or entertainment I get from that particular blog hasn't crossed my mind. I would argue that using a blog service lets you as blog writer concentrate better to the main attraction (i.e. your blog posts) and not worry about technical details, layouts and trying to get problems solved with sometimes quite unresponsive tech support especially when using cheap service provider.
