KDE4 spotted!
Almost everyone at LGM is using Gnome -- there are few KDE desktops to be seen. And no KDE4 desktops at all. Until now: Dave Coffin of DCRaw fame uses KDE4! And XV -- ages since I last saw that.
Dave's presentation was another very satisfying, very technical and deep presentation. This year had quite a good mix of presentations at different levels.
