How short can you get?

With the popularity of Twitter, companies are working hard to keep their deep links below 140 characters to enable ULR sharing. However, this seems to cause a problem because scamming and phishing can be a problem. Also, there are several sites where a URL can be fed into a code maker and it will generate a shorter URL that will redirect people to the desired site. In some cases there is a small fee for doing this but hey, it works and that way people can spam Twitter users!
