Since it is currently en vogue to ponder about the use of the KDE name, I have no other joice to join the fun ;)
While the focus has been on the topic of applications, it also applies to developers:

For the record:
Since it is currently also en vogue to suggest alternative naming schemes: how about calling application maintained and released by the KDE team KDE.org applications?
