Instead of that sorry excuse of an article, here is the proper long-read about spaces.

Albeit in Russian, all modern browsers support live translation — should be fine.

BTW typography is very important to Russian designers and developers.

Many install special typography layout (with “right alt” layer for the symbols) to always enter correct m-dashes, quotes, and what have you.

There is even an ongoing meme with a woman crying “I don’t deserve such treatment, that’s how I’ve always written” when her flawless typography was considered ChatGPT in the making:

Wikipedia articles, and encyclopedia articles in general, are not meant to be "proper long-read" articles. They're meant to be short, descriptive passages that give you enough of an overview to know what the subject is, and directions on where to find more information should you want it. This is not a sorry excuse, it's just the nature of what an encyclopedia is.

FYI, you don't even need browser translation. The piece already has an English version available. There's a language toggle in the navigation bar, and the English version is here: https://type.today/en/journal/spaces

Also, liked the article!
