Programmers are humans too

Imagine, hypothetically, that programmers are humans ... despite all evidence to the contrary:

 

* They work at night, and sleep during the day;

* They only need 2 hours of sleep;

* They survive on a diet of pure caffeine and sugar;

* Many actually enjoy using the vi editor.

Also pretend, just for a moment, that their chief method of communicating with a computer was programming languages.  What should you do?

Designing notations, including programming languages, is not a purely technical exercise, especially since humans have to use them.  Human-computer interaction metrics such as speed of use, error avoidance, and enjoyability can be applied just as well to notations as physical devices and computer programs.
