I have rewitten large parts of the feed generation for Nukumi.
As a side effect, I had to break the <id>s of the Atom feed.
This is bad, but it had to be done — better sooner than later.
I apologize for the inconvenience.
BTW, next week, my old blog will vanish (Yeah, that can even happen to blogs which are not hosted by weblogs.com :P). Please update your links to http://kronavita.de/chris/blog.
