It does happen. I've been reading jQuery source recently as a learning exercise, for instance.

This. I like this. It's sort of like an OOCSS Bootstrap.

No. Not at all. OOCSS focuses on patterns that are reproduced in the page (or site) multiple time with little variation of look or positioning. This is everything but that.

From the looks of it he originally used 'carnal' in the title, then recognised his mistake, but had already made the slug for the URL before he changed the error.

I'm struggling to understand why you're saying you can't build a REST api with Django out of the box. It's easy to serialise python data to pretty much any format. Why do you need Django to do any of that for you? Things like RESTapi add extra features, not core REST functionality.
