Usability: Everyone is for it
This week's Computer Weekly: According to Phil Crosby - reported in 'Downtime' - software is like sex because "Everyone is for it", "Everyone feels they understand it" and so on.

OK, let's apply this to usability:

Usability is like sex because:
Everyone is for it. (Under certain conditions, of course.) Like democracy.
Everyone feels they understand it. (Even thought they wouldn't want to explain it.) Like teaching.
Everyone thinks execution is only a matter of following natural inclinations. (After all, we do get along somehow.) Usability is just common sense, right?
Most people feel that all problems in these areas is caused by other people. (If only they would take time to do things right.) And they would never commit the errors made by others, not in a million years.

Yeah, I think that's a fairly accurate representation of how things are ;-)
