I was just looking at that same list. I'm surprised Lua is that low considering how many applications embed it.

The reason those rankings are (mostly) useless is that it's based on search engine hits. An active, effective community that for whatever reason doesn't generate a million and one blog entries a month will not perform as well on the index. This makes it very useful for indicating fads in programming, but not reality.

There's also http://redmonk.com/sogrady/2017/03/17/language-rankings-1-17... which uses # pull requests on github with # of tags on Stack Overflow. Another biased methodology for sure, but it paints a different picture.
