Luis: How do I keep informed about Gnome News? Well I used to read footnotes, but now that that is agregated into Planet Gnome, I just read Planet Gnome.
I'm also subscribed to loads of mailing lists: desktop-devel-list, usability, nautilus-list, gnome-announce-list, rhythmbox-devel, gossip-devel, foundation-list, gnome-bugsquad and maybe a few others. I'm also CCed on lots of bugs, and I've created quite a few myself. So I get plenty of Gnome related e-mail.
Last but not least, I spend a whole lot of time on irc.gnome.org so pick up a lot there from talking with hackers and users.
