It's funny that they say that because I would say, if I did call things hipster, that this was hipster. Typically hipsters are defined as people that go against mainstream. Well this is pretty far from current, popular app dev environments.
I was actually thinking this sounded incredibly hipster -- heading towards some (in my opinion) completely inappropriate minimalism, where writing vaguely secure code will be almost impossible, and you end up having to write huge amounts of simple base code which should really be provided for you.
Yes, that's harsh, but I think starting new web server projects in C nowadays deserves the harshness.
