Summary: URL shortening services, such as TinyURL, are a problem. The folks who have proposed rev=canonical have written some useful software around it, but rev=canonical has some potentially insurmountable issues. I suggest the following posts if you find this at all interesting: The post that drew attention to URL shorteners (by the creator of del.icio.us) http://joshua.schachter.org/2009/04/on-url-shorteners.html A summary of the work on rev=canonical, with good links and also a new bookmarklet http://simonwillison.net/2009/Apr/11/revcanonical/ An interesting post that makes the case for rev=canonical http://adactio.com/journal/1568 An interesting post that makes the case against rev=canonical http://www.mnot.net/blog/2009/04/14/rev_canonical_bad "I (used to) like rev=canonical” http://decafbad.com/blog/2009/04/13/i-like-revcanonical An interesting assessment of the issues involved http://intertwingly.net/blog/2009/04/14/Canonical-Reverse-Or-Wisdom-Defying-Shorturl I'm not sure what happens now, but I hope the conversation results quickly in as much software as is needed.
