If you are in Berlin on Friday you should also attend our GNOME 3.0 Release Party. It's at the world famous c-base, in the remains of an alien spaceship that crashed into Berlin 4.5 billion years ago (no kidding!). We've got Ubuntu's Daniel Holbach as DJ, and a few folks from the GNOME community will do a talk or two (including that annoying dude who created Avahi, PulseAudio and systemd). We even got Mirko Boehm from the KDE side to say a few things. And there are going to be GNOME 3 goodies! How awesome is that? See the wiki page for further details.
And here's your homework until Friday: Try out GNOME 3.0!
