I would like to emphasise this. Usability cannot be learned by
watching people who have no usability issues. Usability is learned
from watching the people who struggle. Making the system usable by
them will make it more usable to everybody, even those who wouldn't

Effective usability will never be done in big changes that can be
vaunted in blog posts. Effective usability is done in hundreds or
thousands of tiny changes, each of which individually contributes
negligibly, but together form a whole.
