When you create a new WordPress blog you will find that if you jump Settings > Writing and then look down to the bottom of the page there is a section called ‘Update Services’.
From the Codex:
“Update Services are tools you can use to let other people know you’ve updated your blog. WordPress automatically notifies popular Update Services that you’ve updated your blog by sending a XML-RPC ping each time you create or update a post. In turn, Update Services process the ping and updates their proprietary indices with your update. Now people browsing sites like Technorati or Sphere can find your most recent posts!”

By default it will contain http://rpc.pingomatic.com as shown on the image above.
But there are lots more services that you can notify too. Below is a list you can copy and paste into your update services list to gain increased exposure for your new posts.
