Here is the list of blog ping servers I use. Ping servers are services which are automatically notified after a blog post is published. They help to increase the exposure of your blog to a larger audience. The list below is filtered from various online lists after I checked their current availability. I also removed services which are already pinged by pingomatic as redundant ping will make this servers rather unhappy. So without further ado here is my power blog ping list:
http://rpc.pingomatic.com
http://www.blogpeople.net/servlet/weblogUpdates
http://ping.myblog.jp
http://ping.bitacoras.com
http://ping.bloggers.jp/rpc/
http://bblog.com/ping.php

Let me know if you like to add or edit or remove any servers from this list.
