For the longest time, KDE mostly vanished from the radar of most Linux users and media alike. Why? For many, the evolution to a more modern metaphor for the desktop (such as Ubuntu Unity, or GNOME 3) took precedence over the old taskbar/start menu style. For others, KDE went through a period where the desktop simply wasn’t stable. The evolution from KDE 3 to KDE 4 was a bumpy transition that knocked a lot of users off the bandwagon and onto smoother rides.
