Mark,
Only standard sharpening was applied by LR on output to the web. My workflow 
for 
MF is that I do all raw processing in Capture 1. I do no sharpening at all 
there. Then I bring it into CS5 and do layer adjustments; no sharpening 
there. 
Then I import to LR just to organize stuff and throw it onto a web page; 
standard output sharpening done there.
That's it; honest Abe!

You didn't do any sharpening after hand?
How about during hand? Check all your prefs? Menus in your menus?
Its got a very hard look to me. Really verging on too hard.
