My friend was asking me where to ping when he posts a new blog entry.  I told him to go out back behind the house if he wants. hehe…ok, that was a bad joke.  But anyways here is my list of ping services I use:

• http://blogsearch.google.com/ping/RPC2
• http://rpc.pingomatic.com/
• http://rpc.technorati.com/rpc/ping
• http://www.bloglines.com/ping
• http://ping.feedburner.com

If you are using Windows Live Writer then add these under Tools/Preferences/Ping Services.  For Wordpress go into Options/Writing and add them to the Udate Services section.
