Adobe hints are used in rasterization of an outline. They try to
ensure that strokes have the same width, and so on. But they can't fix
an outline designed for 72 point to work well at 6 point. When you
reduce sizes, you need to make open spaces larger, thins relatively
thicker, and so on.

However, Bitstream's hints are much more intelligent, and in practice
alter the way they rasterize an outline at small point sizes to avoid
some of the problems with using an outline designed at a different size.
That's why Bitstream's fontware produces better looking output than
Adobe or Compugraphic.
