URLXL.net - Shorten that url and then SHARE IT!!
URLXL.net is a site that attempts to shrink your url and then share it. Similar to other websites that shrink your URLs we shrink them but we use slugs instead of numbers. So what happens when you are trying to use the same slug and/or URL that someone else submitted? You are given the opportunity to add that user[HTML_REMOVED]s URL to your collection. You can also [HTML_REMOVED]Follow[HTML_REMOVED] other users, which allows you to get a feed of all your [HTML_REMOVED]Follow[HTML_REMOVED] URLs combined into one feed. There are a couple of other things but you have to visit the site to find out. I almost forgot its powered by Google App Engine.
