Short URL’s are helpful when a user is limited to a certain number of
characters, such as on Twitter. When using most Twitter applications,
whenever a long URL is entered in a tweet, it is automatically
shortened, using a shortening service like bit.ly.
These shortening services usually take advantage of recently released
TLD’s to get a domain name as short as possible. Recently, Google
jumped on the bandwagon with goo.gl, another URL shortening service.
