According to some statistics [0], Wordpress is used on 41% websites in the world. That’s a lot of websites! Even if those numbers are inflated, It is still likely the most popular PHP app in the world. It is not disingenuous to judge a language by its most popular application.

I wonder what fraction of PHP programmers today mostly work with Wordpress.. and how many PHP jobs involve maintaining Wordpress apps.
