Hacker News is a social news website focusing on computer science and entrepreneurship. It is run by Paul Graham's investment fund and startup incubator, Y Combinator. In general, content that can be submitted is defined as "anything that gratifies one's intellectual curiosity" [1]
99% of the technical articles posted on HN are very accessible if you have just the very basic understanding of CS without diving into any specific areas. I.e., lots of breadth, but little depth that is required for understanding (even if the articles themselves dive into depth).
I would count knowing the JPEG spec as a depth, rather than breadth.
