Programmers are responsible for the GIMP GUI. Fuck programmer-designed user interfaces.
Programmers designed the pre-Office 2007 GUI. Result? Microsoft fielded a hojilliion support calls with people making feature requests for features that were _already implemented_. But nobody could figure out where they were or how to work them!
Functionality that people can't use and can't discover is absolutely useless. Let's hope for more designers and less developers.
