Hm, now that you mention it...
But in all seriousness, you make a good point. Not everyone will be interested in running a game in the Nine Swords world specific to the Tome of Battle, and lots of people dislike the ToB specifically because they don't like the fluff.
So we'll stick to the disciplines. I'll make note of those that have fluff already, and then let's decide who should do which of the remaining.
Is anyone interested in fluffing a particular discipline or disciplines?
Edit: In the list of disciplines at the top of this thread, I've added the "fluff status" of each discipline.
