This plugin allows you to generate shortlinks for post/pages using URL Shorteners (e.g. Bit.ly, Su.pr, YOURLS, Goo.gl and many others).
For the most updated list, please check: http://wiki.fusedthought.com/docs/url-shortener-wordpress-plugin/faq
Normally it's only depreciated when the shortening service is down for a prolong period of time. However, if there is a request, I will definitely consider it.
