Regularly (and dependably!), posts about knots make their way to the front page, often to the top … it's nearly in the same mold as "articles warning about lending/housing behavior".
If one has a hacker mindset that extends outside of startups and technology, knots are pretty dang useful. I use them all the time in DIY projects, camping, etc.
Knots take a nearly 1-dimensional object and generate a 3d structure that is both durable and potentially useful, sometimes bordering on life-changing. That's super cool.
I think a lot of us also have a bit of a primitivist streak, and knots are a low technology that can replace a lot of higher tech and still get a lot done (compare to HN's enduring fascination with Forth).
