Yes, ABSOLUTELY! JPEG is designed
for things that have smooth tones, like people and outdoor photographs. It is horrible
with anything that has sharp contrasts like letter outlines and line drawings.
Furthermore, it is utterly unfit as a storage format for files being edited (since every
save/reopen loses more detail). It's just barely tolerable as a source file format in
digital cameras, and it's of course appropriate as a final format for continuous tone
photo-like images.
It's always amazing to see ignorant "graphic artists" uses JPEG for
corporate logos. Those go into the "you get what you pay for" bucket.
