Have to put in my two cents. My husband is a writer and he has a copy of Scrivener. Being that he is blooking (two novels, one serial, and a bunch of short stories) there was no easy mechanism for him to transform what he had done in Scrivener to his blog.
If he was continuing to concentrate his efforts solely on writing and not be concerned about publishing to the web, hands down Scrivener is the best tool for the job. But, that ability is lacking when someone wants to take what they've produced and publish it.
Hence, he is now a die hard user of MacJournal. Everything has been converted from Scrivener over to MacJournal and this is now where he writes primarily. Not its intended use, but for quick and easy publishing ability in a blook format - definitely the way to go!

If you really want to expand on the capabilities of RW, check out some of the addons that are out there. I have quite a few but have unfortunately shifted gears to writing most of my sites in Wordpress. I DO know though that when I need a static site - RW will be sitting there waiting for me to fire it up.
