Your first link pretty much says it all: barebones website 5 years out of date, no docs, no resources, no community links, no indication that this project is even alive. To top it off the project is named after one of the most annoying creatures on the face of the Earth. This is a marketing issue.

The problem for older languages is that the bar for what's expected of a language has risen substantially. A long time ago, languages weren't even expected to have implementations. Today, not only are implementations expected for all major platforms, languages are also expected to run on phones and the browser, include package managers and library repositories, have a language server implementation and editing modes for all major IDEs, be open source with active development, provide extensive documentation on the scale of a book, and also promote a vibrant and active community. Oh, and to top it off, users don't want to pay for any of that. It's just expected, which is why most languages these days only come out of large tech companies that can afford to fund all of the above with no expectation of profit.
