I never researched much on pinging with my Wordpress blog. I been using pingshot in feedburner to ping services. But Technorati DOES NOT update my articles. Last ping was over a month ago from when the blog first started out.
I installed a wordpress plugin called the Maxblogpress ping optimizer and turned off pingshot. Here is the sites I pinged with the new plugin (forced ping)
http://api.moreover.com/ping
http://api.my.yahoo.com/rss/ping
http://blogsearch.google.com/ping/RPC2
http://ping.bitacoras.com
http://ping.feedburner.com
http://ping.syndic8.com/xmlrpc.php
http://rpc.blogrolling.com/pinger/
http://rpc.icerocket.com:10080/
http://rpc.technorati.com/rpc/ping
http://rpc.weblogs.com/RPC2
http://topicexchange.com/RPC2
http://www.blogdigger.com/RPC2
http://www.blogoole.com/ping/
http://www.popdex.com/addsite.php
http://www.wasalive.com/ping/
http://www.weblogues.com/RPC/
http://blogping.unidatum.com/RPC2/
And here is the log results of the ping:
http://api.moreover.com/ping could not be pinged. Error message: "parse error. not well formed"
http://api.my.yahoo.com/rss/ping could not be pinged. Error message: "transport error - HTTP status code was not 200"

http://rpc.technorati.com/rpc/ping was successfully pinged (extended format)
http://rpc.weblogs.com/RPC2 was successfully pinged (extended format)

Why won't these ping? And why doesn't my site show up in google blog search, icerocket and other services. and WHY won't technorati update?! I've even pinged them directly on the site many times.
