Planet WordPress

I found out about Planet WordPress from a recent blog posting:
http://wordpress.org/development/2004/12/planet-wordpress/
What I don’t know is what feeds are there for this meta blog? Also an OPML file would be nice with all the the feeds.
There seems to be an RSS 2.0 feed at:
http://planet.wordpress.org/rss20.xml
But it does not seem to be up to date and it has syntax errors.
