I don't write drafts (on here, or even when I'm writing someone who's paying me to write it). Maybe I do kind of "write a draft in my head", but the point is I don't write one on paper (oops- the screen, I mean).
Anyway, I always type Hubs into Word Pad and paste them in here later. Sometimes I'll first temporarily paste one into Word in order to get any errors there are to catch. Then I'll paste it in here, run the spell-check here, and maybe get another typing error or two.
Writing Hubs directly on here (or any writing site) is risky. There's always the chance you'll lose whatever you've written. Writing offline first also kind of forces you to have a copy of everything you write, file it, organize it, etc. etc. Keeping at least one copy is always a good idea. You never know, as they say.
