Just about everyone in the social networking space uses URL shortening applications. Now, I know there are tons of sites out there that do this, but this one is a true gem.
Su.pr is a great new application by StumbleUpon (someone who we already know, love and trust) where you can shorten, track and promote your URL’s. Su.pr is tied to StumbleUpon and your users have to capability to rate and review your posted links. It also has a time saving feature allowing you to schedule your posts for a later time and date for Facebook and Twitter. It encumbers many tools that normally multiple sites are needed to accomplish the same results.
You can see the functionality of the interface here: http://su.pr/9rtTZk.
