Smart Update Pinger plugin which will ping these services only when you post the article not when you edit it is also recommended. It also has one cool feature – you can check smart-update-pinger.log file found in your wp-content folder of WordPress installation and see if any services refuse ping request for your site.

In that case you can simply remove them from the list not to waste time pinging them.
