Are there any websites indexing "underground" languages to indicate their current adoption status ? From "only the language developers and their friends are working with it, for experimental projects", to "some fancy startups are using it with good results thanks to its cool new features" ? I don't mean it as a way to depreciate the work people put onto those projects, but it would certainly help with understanding what one's expectations should be. If i take OP example : adding a new target to a language that's already heavily used in some startups in production doesn't mean the same thing than if the language is just used for toy projects and experiment. We all know how hard it is to reach production-grade quality (for pretty much anything), and how many good ideas simply collapse on the face of overlooked details from the real world.
