Best URL shortener

There are lot of online services to shorten urls such as tinyurl, memurl etc. The main advantage of URL shortener is to break a long URL in to some characters which enables you to posting in a small space.

However most URL shortener services includes their full URL in to shortened URL and it is not short at all.

Recently tweak.tk started a URL shortener service that lets you short the domain name in to very small pieces. Such as
http://typ08.tk

This is really helpful if you do not want other scraps insert in to the breaked down url.
