How? If you shorten URLs, you have to be able to reconstruct the long
ones. Compression can't do that to arbitrary lengths. Somewhere there
needs to be the rest of the information.

There are many places where there are limits (hard or soft) on message
lengths. Some of us still use MUDs and 80-character line limits.
Business cards or other printed media need to be transcribed by hand.
Dictation of URLs becomes virtually impossible when they're
arbitrarily long.

Sure...... if you control the destination server. What if you're
engaging in scholarly discussion about someone else's content? You
can't change the canonical URLs, and you can't simply copy their
content to your own server (either for licensing reasons or to
guarantee that the official version hasn't been tampered with).

So URL shorteners are invaluable tools. However, I'm not sure what
this one is that others aren't.
