Agree! In fact, I would appreciate more well written articles explaining basic concepts on the front page of Hacker News. It is always good to revisit some basic concepts, but it is even better to relearn them. I am surprised by how often I realize that my definition of a concept is wrong or just superficial.

Also it's nice to have a set of well-written explainers for when someone asks about a concept.
