Thanks for posting the link--there was at least one problem I know I have (the multi-used words)...I'd vaguely realized I was doing it but didn't realize how much it could stand out after awhile.

(My word, by the way, is "quick" and all variations thereof.)

I also worry that a lot of my prose is flat, but that tends to be my own overboard self-criticism, I think (or hope), more than anything else.
