Which update services do you ping when you publish to your blog? I am using a self-hosted Wordpress blog and have these listed: http://rpc.pingomatic.com/ http://rpc.technorati.com/rpc/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/
The key to a successful blog is writing articles people are interested in. What you need to be careful of is over pinging. Many of the aggregators you have listed (some twice) ping the same services. Depending on how often you update your blog some of them may view your submissions as spam.
