Well, considering most of the government uses a Microsoft stack I'm not surprised. Besides, their categorization is pretty well-done. Reddit and sites such as this one are harder to use for people who don't write software or regularly browse the internet. (And, considering Stackoverflow is based on a Microsoft stack very similar to this site, it's slightly silly. Pick the right tools for the task and a dev stack you enjoy).

Don't you get it? Reddit is pro-Obama, so obviously they couldn't use this communist rubbish.

True patriotic capitalists use proper respectable Microsoft software for everything.

(note for the humor-impaired: I'm poking fun at both the typical Tea Partyer, and the the pointy-haired types (see Dilbert) that get to decide what software to use.)
