To make a long story short: Shorl makes long URLs short. bookmarklet

To make it easier to create a shorl, drag this link (don't click - it doesn't work like that) to the links toolbar in your browser. Voila! By clicking the toolbar link, you'll get a shorl for the page you were at, automagically.

Here it is: shorlify

You can also just store the link as a bookmark/favorite. It will work the same way.
