Usability. (In response to ESR’s CUPS
Horror. Compare Why Free Software
usability tends to suck, mentioned here a while ago.)

UI development is the hard part. And it’s not the last step,
it’s the
first step. In my estimation, the difference between:

• software that performs function X; and
• software that performs function X, with an intuitive
  well-designed user interface

isn’t just a little bit of extra work. It’s not even twice the
work. It’s an entire order of magnitude more work. Developing
software with a good UI requires both aptitude and a lot of hard work.
Raymond acknowledges neither.
