A few comments, I hope someone can help.

1) what's this broken link at the top ?
http://nouveau.freedesktop.org/png/ll.png

2) what's up with the feed reader, it doesn't seem to work at all :
http://feed43.com/nouveau.xml

3) the news are terribly outdated, they seem completely useless now
We might as well just remove them if no one can update them or if there is never
anything news-worthy.
