I agree with this. The clouds are not particularly sharp (which would
be some sort of contradiction anyway, wouldn't it?). I think it is
some function of the way the light falls and the contrast that
suggests sharpness.

That's a very interesting study. Thanks for sharing that.

Your condescension is breath-taking at times, Moose. 8/
The impression I get also is that the web image is a little sharper
than the original when one looks at the original fullscreen. I've put
a new version cropped 3:2 out there which has been reworked from the
16-bit TIF output of raw conversion. In addition to the different
crop, I brought the overall values up a bit more. To me it appears a
little softer overall. There is no difference in sharpening
procedures. The appearance of a halo in the previous version is an
artifact of the way I sometimes use the highlight-shadow tool (and the
fact that haste makes waste), not over-sharpening.
