Peter has upgraded his blog to the latest version of Moveable Type. As a result, his blog now pings weblogs.com via XML-RPC whenever he makes an update. blo.gs grabs the weblogs.com changes.xml file once an hour and uses it to generate a smaller file listing only sites on my blogroll. My site then grabs my personal favorites.xml file once an hour and uses it to render my blogroll ordered by the time each blog was updated.
Isn’t XML fun?
