Ooh I really like the triangle one. It's the top voted answer, so I guess I'm not alone.

In fact, I think I really enjoy specialized notations. I care about how ideas are expressed, sometimes even more than the ideas themselves. Sheet music, SQL, creating DSLs in Lisp, Hoon code (controversial here).

There are counter examples. For example, I adore coding in SQL, but ORMs always feel super gross. And isn't Paul Graham's adoration of Lisp kind of a programming version of the Sapir–Whorf hypothesis?

Whatever, and in Sapir (and Whorf)'s defense, how "debunked" is linguistic relativity anyway?

Whatever, I'll keep accruing beautiful new symbols and vocabularies and aesthetics for saying things that were previously unsayable and discovering new ideas to put together elegantly.
