How does 'tinyurl' work, then, to compress such a monster into 4 letters?
I rather doubt there's any compression going on - just a big index, rather. If they use upper and lower case letters and digits then they'll be able to manage around 15M URLs before they have to go over 4 characters (or use a new domain).
