My question to you all is:
I've often been told I am not one of these "average users" because I create and distribute software. Who is then? Is my brother the level designer an "average user"? Is my fiancée the accountant an "average user"? Is my mother the tutor an "average user"? What exactly is the criteria to be in the group of people so many seem to be trying so desperately to make software for?
Often hand-in-hand with this idea of an "average user" is the concept of "user friendliness". In fact a drive to make our user interfaces even more "user friendly" is what has caused the radical changes in the Gnome desktop (and of course the creation of Unity).
