Even so, most users cannot comprehend URLs. How many of you can
decipher the URL to a dynamically generated site? I've seen a lot of
users in tests in my 9 years of Web development, and few can really make
guess the right path from a 6 possible matches. The autosuggests need
some smarter logic to know when a URL isn't worth suggesting. If you
have shopped at amazon.com, try to type a URL in your browser, you'll
see my point.
Some browsers offer a portion of the page title, but the user never sees
enough to make a good decision (about 12 characters for Galeon).
Sometimes it's because the site has very long titles which prioritize
brand and taxonomy over the title of the content. Sometimes it's
because the site doesn't make use of titles, eg. 'Footnotes -
www.gnomedesktop.org' is the title of all news at the afore mentioned
site. I know we can not make site's have good titles, but they are more
meaningful to users.
I think the same is also true of a file system. The path is not nearly
as important to the user as the destination. I want to see the title at
the of the end path, not the beginning.
I really like the Epiphany keyword/bookmark approach because it offers
titles that the user does understand (because the user made them).
Saddly, Epiphany doesn't even include titles in it's autosuggestions.
