Jason Kottke and his guest-blogger, Greg Knauss, discuss the blogging dialectic.
Writers and editors
After reading Greg's thoughts, Meg reminded me that Rebecca Blood had made a distinction between filter-style and journal-style bloggers in Weblogs: A History and Perspective. If you want to generalize outside the realm of weblogs, they're both talking about the difference between writers and editors.
I'm certainly well defined as residing in the editor/dj mode of blogging. Mostly because I have another couple jobs that subsume my time, and actually pay me livable wages, well, nearly pay livable wages. I tend to blog like I talk, which is more in aphoristic, sentence form than in paragraph, essay form. [redacted rambling paraphrased anecdotes and life-history]. I can write my way out of a paper bag, or so I delude myself into believing, but fail to see it as a requirement for blogging.
