Why does HN seem to be so much more interested in homotopy theory and related fields than other fields of math? I'm not a mathematician, and my understanding is that this "area" (including algebraic geometry, algebraic topology, and related areas of mathematical logic) represents a very small proportion of what career mathematicians actually work on. Does HN just like this subject because it is trendy? Because of its reputation for being difficult? Because of perceived connections to programming (of which I believe are generally exaggerated)?
