Everyone can use it in any way they want. If there are 100 million blogs out there, there are 100 million blogging styles and 100 million ideas what blogging "is". And anyone who dares tell others how to do it incurs the wrath of the other 100 million who are NOT going to be told what to do. Blogosphere is democratic - the voice of millions of individuals who finally have the ability to have their voices heard. They will never accept any authority telling them how to do it and what they can or cannot write.
