Script Summary: Remove Yahoo Link Tracking (ylt and ylu in URLs)
Based on jk-'s script (#3642 at userscripts.org), but modified for a shorter ylt string and to also remove the ylu strings.
Update 2 April 2007: The ylt strings got longer and the ylu strings have disappeared; updated to take these into account. However jk- has also updated his script to take care of this more elegantly and I recommend you use it instead: http://userscripts.org/scripts/show/3642
