Ping-o-Matic is now not only a HTML form-based service that you can use to notify multiple sites of your new weblog entry. This weblog entry let us in on the new ping URL that you can use to replace the long list of URLs you're currently pinging everytime you make a new weblog entry.

This means no more waiting for your weblog software (be it Movable Type, WordPress, or something else) as it pings multiple services.
