I have never thought of writing any other way than into a text file first. My typing is bad enough that it would take endless edits to fix it going straight to post. Plus, I like to use at least one beta and writing straight onto the board would obviously prevent that from happening. I agree that a plotline can end up twisted in a new way with a few interesting edits. However, I have lost enough stuff on computers in other ways so that I am an obsessive save-after-every-paragraph kind of writer.
