You "subscribe" to what you want to read and to be informed about. This enables a personal "pull" model of communication. In contrast, e-mail is a "push" model and you do not select who sends you mail. More like a subscription to a magazine or newspaper where you like to read a few columnists or you just want to get an overview of what is news today.
Blogs also serve as an organized way to retrieve the rich store of archived material as the blog grows with information over time.
SpanBlog software allows the reader to interact with comments to your posts. (A blog owner may turn off this feature) Have you ever wanted to respond to an author with your opinion?
