A coworker today introduced me to TinyURL.com.  Tired of trying to email or link big, long, ugly URLs?  Go to the TinyURL Web site, enter the URL, and receive a new, permanent, and much shorter URL in return.  All through the magic of redirection.  For example, the URL to my main Random Notes page (http://www.mischel.com/diary/index.htm) is also http://tinyurl.com/m1oa.

This assumes, of course, that the TinyURL service remains available and that the servers are online.  Cool stuff, regardless.
