URL shortening services are becoming quite popular now micro-blogging services like Twitter have gone mainstream.

Yesterday, I discovered yet another URL shortener service from called u.nu - probably the shortest domain possible for such a service.

Unfortunately, u.nu don’t offer a bookmarklet directly on their website so I created one myself.

Drag and drop the u.nu bookmarklet to your address bar and you too can save even more characters when posting links to Twitter.
