I was looking at the technorati site, and in the "Get Listed" section, they have the following info:
You can also use Technorati's XML-RPC interface, which means that you can automate this process by using your weblog software. Enter http://rpc.technorati.com/rpc/ping into your weblog tool's configuration for Pings and Notifications. Since the exact configuration steps necessary are different depending on the tool you use, you can check the Technorati developer's wiki or the documentation of your weblog tool for more information.
The developer's wiki only mentions b2, not WordPress.
Does anyone know how to implement this correctly in WP?
