Ping-O-Matic is Offline
Technorati lets us know that Ping-O-Matic is off line. If you didn’t know this and you still want to make sure your pings reach Technorati and other blog engines, you need to ping them directly
Technorati also makes a note about WordPress specifically:
If you use WordPress and have not changed your ping settings your update notifications are currently not reaching any services, including Technorati and many online aggregators. To add Technorati’s ping server to your list of update services please follow the instructions on our WordPress ping configuration page.
