It's common practice to sharpen thumbnail images. They looks much better then. You can do it with this trivial code:

// sharpening
$matrix = array(array(-1, -1, -1), array(-1, 24, -1), array(-1, -1, -1));
imageconvolution($thumbim, $matrix, 16, 0);

Probably this can be also done in the plugin assigned to "upload_attachment_do_insert" hook.

I think this should be an option in the ACP

It can be always switch on IMO, see the nice explanation here: http://www.smugmug.com/help/display-quality

Hmm, looking around, it looks like PHP's imagecopyresampled function does a bilinear resample. A bicubic/lanczos resample would be much better, but seems like PHP can't do it.

Sharpening isn't a bad idea though
