I will never not post this picture on this subject. Skimmed through the article, seems well written and will read it later.

Edit: did read it through, and don’t necessarily agree. I don’t think about any of this when writing lisp code. Emacs deals with my parens, as does paredit and structural editing. This discussion ignores the things that makes lisp work: s-expressions. By changing this main feature, one destroys lisps best feature.
