Maybe I'm the last to stumble upon this... anyway: Nabble is monitoring gentoo-dev offering a search and browse interface and two feeds for it: "new message" and "new threads". I was thinking the "new threads" one could be a great tool to Gentoo users that are not interested in every single mail (I currently am) but still would like to keep on track of the big picture of gentoo-dev. I would have needed just that for the Google Summer of Code mailing list.
