That graph can't be right. Everyone knows it's a toss-up between Rust and Clojure. :)

Sorry, but the second largest "language" on that graph is HTML/CSS. I mean that's not even a programming language.

That's a poor stats to be polite. SQL is no programming language, PL/SQL and its variants are. Without scripting languages you can't embed much logic in it.

I also wonder how they count multi users, I can easily mark 10 of those if not more.

> HTML/CSS were the most commonly used programming languages

I am sorry but that can't be taken seriously, then I know a ton of Excel developers, and wait till I get to Powerpoint ones.
