I've been thinking about what KDE is. Or what it means to be a "desktop environment" at all. KDE has many faces (and we're not just talking about kde:KJanusWidget :). The windowing manager (and associated KDE Panel) is the public face, but the infrastructure in
kdelibs that makes the key applications (KMail, Konqueror, konsole, kdevelop, and lots more) not just possible, but consistent and reliable. The toolset in kdevelop, and the developer community are key parts of KDE too.
