I'm a bit late, but I also want to share some of my impressions from LinuxTag last week.
As always it was fun. It's always nice to meet with other OSS developers, be it gnomes, X devs, the mplayer guys and of course, our KDE fellows :-)
A big thanks goes to the people who organized our KDE booth, so especially to Joseph Spillner this year. We had four nice boxes there, two running SUSE, and two running kUbuntu, both very nice although quite different distributions.
