updo.debian.net is the new url for the upstream Planet Debian that I've been running for a while, aggregating some of the blogs of upstream software authors. Now it's a wiki so it's really easy to add new feeds to it.

Oh and BTW, if jwz's posts get on your nerves, a jwz-free version is hidden in a link at the bottom of the page. :-) And other feeds could be pieced together if you're only interested in say, the linux hackers, since posts are tagged and can be filtered by software or author.
