I don't really understand why anyone would have an intensely personal blog online... the journal-style ones, in which the author bares his soul for the world to see. What point or purpose could there be to dumping one's least developed thoughts and one's most ethereal dreams into a little box made of HTML? And then clicking the little "publish" button, like one's blog were a valuable autobiographical resource for some famous or controversial person?
I sometimes think that the plethora of personal, journal-like blogs devalues the nature of a blog.
Therefore, I keep most musing between the pages of my real-life, tangible journal, of paper and ink.
