It doesn't matter which is more popular, people. We're taking about two Free environments here, with clearly different goals and directions.
Perhaps Microsoft tought you that a desktop must rule 95% of the world and all others must die, but I see no problem in having GNOME with a 30% market share, KDE with 30%, GNUstep with 10% or whatever. GNU/Linux with 50% and *BSD with 20% As long as we're living in a world with free software and open standards, we can use whatever fits best (and for the people who don't want to choose, no problem, they don't have to).
