Tiny URL

I came across this site called tinyurl.com, It allows you to create a “tiny” URL for another link that may be pretty long. This tiny url is also a permalink. I think this is a useful URL shortening service and I like the “preview” version of it better. To check it out…click the link. http://preview.tinyurl.com/5djd3v
It would be cool, if they also add a preview image 🙂 BTW the site does not detect any circular links 😦
