KDE gained a number of users from the Gnome transition. Gnome is gaining
some disappointed KDE users now. When Gnome does their 3.0 switcheroo, KDE
will gain some disgruntled Gnome users.
Something like the tides of the sea.
At least there is a choice.
Sometimes things have to be burnt to make it better. Xorg is doing
something like that right now with similar responses. Usually things get
much better over time, and we forget the turmoil.
