definition of 'blog'

What is a blog? by Tim Jarrett:

"Blogs are personally published documentson the web, with attribution and date, collected in a single place, generally published with a static structure to facilitate incoming links from other sources, and updated with some regularity and frequency from every few days to several times daily. Blogs are generally understood to be subjective, with no authority other than that lent by their author generally. Many blogs consist of links and commentary—comments about something or some entity with a web presence, links to enable the reader to discover the original object being commented on and explore it for themselves. Bloggers leave link trails, hyperlinks back to the subjects of their commentary, and the link trails enable others to go beyond the blogger’s subjective opinion and find the original source so that they can evaluate it and form their own opinions."

Note the emphasis on connectivity and open communication. My emphasis in bold.

I particularly like the definition of a blog as a collection of "personally published documents". This definition brings forth an objective and not so circular definition. The best part of this definition is that does not define blogs in terms of daily personal journals and/or personal diaries.
