I've already switched from Word to OneNote to prepare my blog entries. I didn't like maintaining more than one idea in a Word doc. I get a few ideas going at a time, and I create a page for each one in a section I have dedicated to my blog. When I get a chance to flesh them out, they still have their own pages. When I am ready to post, I move them to Word, let Word's more aggressive and capable proofing tools check 'em out, add any hyperlinks I need, then paste them in the blog tool. I miss the speller-based AutoCorrect in Word when I type though - Onenote only has the basic list-based one. Clearly this experiment in blogging has been useful already. I am inspired to fix my own pain.
