I love TinyURL! and have been using it for years and years.

For the first time today I scrolled down the page a bit, by accident, and saw that you can create a TinyURL! bookmarklet. Trés radical.


I modified the code a little bit so that it opens in a new window.
(Grab it here: TinyURL!)

The actual bookmarklet JavaScript string is:

javascript:void(open('http://tinyurl.com/create.php?url='+encodeURIComponent(location.href)))
