For our Legends of the Green Dragon game we wanted to ping Technorati the daily news. This helps us advertise the game, and gave me a chance to explore XML-RPC and python a little bit. And I do mean a little bit, look at the code
import xmlrpclibCrazy eh? 3 lines of actual code to send the ping, the 4th only to display if the ping was successful. Put the script in a cron job that runs once every day and your all set.
print 'Technorati Replies: ' + response.get('message')
