Nim has been around a lot longer, so I’m not surprised it’s more popular on both axes. > What circumstances are putting some languages above the diagonal while others are below it? I seem to recall them saying that the languages below the diagonal tend to be more widely used for personal projects (lots of GitHub projects), whereas the ones above the diagonal are used more for professional projects (lots of StackOverflow questions). Can’t find it in this article though… maybe this was mentioned a previous edition of the rankings.
