There’s a new function in WordPress 3.0,
the_shortlink(). You can place this in your
single.php theme file to print a shorter URL for the current post if your permalink structure results in something very long.
If you have the WordPress.com Stats plugin installed, you’ll get short links using the
wp.me service. However, if you’d prefer to use your own domain, just turn the
wp.me links off in the plugin’s settings (under Plugins → WordPress.com Stats). WordPress will begin using your default permalink structure instead (unless you have yet another plugin that’s altering your shortlinks). The default structure always works, even if you’ve chosen one of the longer ones.
