I personally know two authors who have approached me about creating simple sites where they can sell their self-published books and blog about their book's content.
That's what I tried to tell students at a bootcamp, but then I never got hired back. They could just fuck off whenever they wanted to go play mario kart, and I tried to tell them that's not what they were paying them for.
that crap is solved in a lot of places, jQuery is no longer the only library, and you don't need to support legacy browsers as much anymore, if at all
Companies are getting more security-conscious because of all the hacks and the pain of keeping old browser support is no longer outweighing the risks of upgrading is my theory.
