To Jabber users:
You can add a jabber user to your roster with this id: s23-wiki@rss-jab.i-pobox.net and you will always have the changes of this wiki in your jabber client :)
Send the message "help" to that user, and you will see other RssNewsfeeds you can add the same way. I have CNN, Slashdot,S23-Wiki etc.. all as a group "feed" inside my jabber client (Psi).
enjoy ;)
