You can also check out my own take on freewriting. I adhere to the Jack Kerouac school of
spontaneous prose.
I think freewriting is a great way to build writing chops and help you write at a moment's notice. I think spontaneous prose is a great way to write first drafts.
Joel I think with the blogs I let my internal editor rise to the surface much sooner than he should. Also even though blogs are conversational that conversation isn't really there when first writing the post. The conversation generally comes after the conversation. I think I'm better at getting involved in the conversation after it's been started than starting it.
Interstingly (to me at least) I'll often compose blog posts in my head as though it's a one to one conversation with a single person. The words flow easily. Unfortunately I usually don't have something to record those word thoughts at the time. By the time I sit down to write the conversation is lost and the writing doesn't flow as well. I have to find a way to get the conversation flowing better while writing. It's probably something that will come down to more practice.
