Googling for things that have multiple meanings is a nightmare, as it can clash with the other meanings. I use Kind the Kubernetes project and find searching for issues related to it tricky for this reason.
We had no reason to worry about making it popular, the effort was staffed to improve developing Kubernetes itself.
As for googling, I recommend adding keywords like "kubernetes" and for issues searching the repo itself or reaching out to the community for help https://github.com/kubernetes-sigs/kind#community
That tool is written in "Go" which also somewhat famously doesn't search well without changing your terms up a bit.
Python is easy 'cause the other meaning is a real noun, so disambiguation is easy.
Kind is a general word, another tech project, and also a programming term.
just an opinion ofc :)
I think you should be fine if you call it "kindlang" or "kind lang" everywhere.
You have to understand that the languages Python, C, and even Ruby have been around for a long time, and I would wager SEO mattered much less when they were being created. This is obviously true for C, and arguably true for the others. To boot, many of them are often searched for with "(programming) lang(uage)" as an associated query.
Similar arguments follow for the rest (Go/Swfit/Rust are supported by big companies, Perl is a unique string, etc.).
What is unfortunate for your language is that Kinds are something associated with PLs theory AND it also seems to be that many people are interested in searching for "what kinds of programming languages are there?" ("kind" in the sense of "type of language").
If I were you, I wouldn't let it get to me – I think this project is cool regardless of name. But if popularity matters to you, maybe try and emphasize "kindlang".
