No, I don't.  You never know when you'll need an image _without_ sharpening
(remember, sharpening degrades image quality).

I don't see much change in the initial sharpening, either, unless it's a
really good scan (read:  a scan of an image shot on a tripod, on slow film,
that really does show detail in individual pixels).  Subsequent 2x
downsamples always show visible improvement when sharpened, though.

I don't like to sharpen images even before I get them into Photoshop.  I
prefer that the raw image be free of sharpening, so that I get as much
quality as possible in that raw image.
