WordPress.org

WordPress generates shortlinks for your posts and pages. By default it uses the ?p= with the post ID added to it, but if you have a rather long domain name this isn't very useful. If you use Bit.ly, or even better, Bit.ly Pro, this plugin will help you: it replaces the shortlink WordPress generates with a proper Bit.ly shortlink.

The plugin replaces the 3.1+ Admin Bar "Shortlink" item with a Bit.ly menu, linking to the stats page and allowing you to share the link on Twitter.
