WordPressManish Jethani explains how short URLs (“Smart URLs”), a new hidden feature in WordPress 2.5, can be used to create short urls.

You may have used URL shortening services like TinyURL.com or is.gd for compressing long URLs so they can be easily pasted into email or shared on Twitter (what with the 140-character limit). Even if you haven’t, you’ve probably wished at some point that the URLs of your blog entries could be shortened without losing their structure.

Well, with WordPress, you have URL shortening built in!
