The average user is disturbed by the sight a 160 bit hash.
When posting graphic images on my blog, I have to name the image twice,
once when I store it on my website, and once when I reference it in a
post. Despite the fact that the names are meaningful and human
readable, and the total number of images is not unreasonably large, I
find it quite difficult to enter exactly the same name the same way
twice. Much of the time the image mysteriously fails to appear, even
though I cannot see any typo, the two spellings right in front of me
look exactly alike.
The end user's instinctive fear of 160 bit hashes is well founded..
