An educational gap, I'm sure ;) ("Bildungslücke" for castaway ;) ). Most people who use Kate use KDE, although it works on (almost?) all QT platforms, like my Zaurus PDA (tinykate), I recommended it once here on PM, where I talked about it's cool support of a graphical regex editor for KDE. I guess I'll forgive you and Abigail-II for not having read or remembered my post, but just this once :)
Kate is really nice for normal editing, but I need cross-platform support, so vim is my editor of choice for that reason.
Graphical editors in general encourage the use of the mouse, which tends to slow people down. If you type really slowly anyway, then I sincerely recommend a graphical editor with syntax highlighting. :)
