I just received an email (about a new blog post earlier today). The questions was “…you mentioned [blog] update services and pingomatic, what is that…?”

For those of us who use Wordpress, it’s a feature you can configure in the writing settings of your blogs administrative area. Simply log in and go to “Settings” – “Writing” and look near the bottom. You will see the following:

“When you publish a new post, WordPress automatically notifies the following site update services. For more about this, see Update Services on the Codex. Separate multiple service URLs with line breaks.”

Many readers subscribe to such services and will see that you have new content posted. By default, Wordpress only notifies rpc.pingomatic.com. The list below contains another 145. Make sure you back up your wordpress files and database BEFORE adding this to the “Update Services” of your blog.
