Paul, I definitely hear you on that. I write almost daily in Day One—just snippets of daily life that I want to remember. Putting it there helps remove some of the pressure when writing on my blog. Later on (sometimes much later!) some of those snippets end up on my blog.
The Ursula K. Le Guin interview I linked to above is really, really worth reading. She describes her work process but also doesn’t get prescriptive about it (especially where she talks about not having a writing schedule).
