> How may employees to Red Hat, Novell, Wind River and Canonical each have? How many developers do Debian, Gentoo, Mandriva have?
Just sticking to the companies (I agree with filipjoelsson in that comparing companies with volunteer organisations like Debian in this is meaningless):
Canonical has 130 employees; Red Hat, 2200; Novell, 4100; Wind River, 1507; Mandriva, 80.
Patches per employee, then, are: Canonical, 0.77; Red Hat, 5.4; Novell, 1.77; Wind River, 0.14; Mandriva, 3.0.
This is still lowish on Ubuntu's part, but when you additionally take in account that Red Hat and Suse Linux have both been around 3.5 times as long as Ubuntu, and Mandriva 2.5 times, the numbers start to look somewhat less drastic than Greg presents them.
