Hi we operate a WP blog at http://www.mother-ship.com/blog and host it ourselves.
Whenever we update the blog does google's blog service get pinged automatically?
If not we can try to set up Google's Blog Search Pinging Service API
but if google is already informed then we don't need to - or maybe there is a simpler way on WordPress?
We do have xml sitemaps plug in installed and this re-writes the sitemap after every post and notifies google, yahoo, bing etc automatically - is this counted as a 'ping' or is that a separate thing?
