Patrick at Deferred Procrastination has got la petite url working with a WordPress Twitter updater. This is a much-asked-for feature for la petite url itself.
The long wait is over, and la petite url version 2.0 is out the door. WordPress users with auto-update can update at-will, and users who haven’t installed it yet (what’s wrong with you?) can get it here. Major changes include: An awesome new options panel, much faster redirects, removing of the old registration for the new one, and a sidebar widget.
