True enough, but if the image requires sharpening? JPG is not a good format, I know, but it is very useful and in fact necessary for the web. I would think it better to convert to JPG and then sharpen rather than sharpen in TIFF and then convert. I haven't tested but I think it would result in fewer artifacts.

Sharpening at that <point was what I was suggesting, before saving as a more-compressed JPG Saving a file as a JPG file at a level of compression involving the least amount of compression would obviously result in much less lost empirical information (e.g., actual image data) than to save at higher compression levels; however, I think it is questionable if the remaining empirical data would represent maximum quality in all cases. But to change the existing data in the original JPG file by sharpening and then resaving the result to a more compressed state is one of the sorts of actions which tends to produce the often found JPG artifacts and deterioration of the image that such a file can produce.
