I thought about contributing to Exercism, adding exercises, syllabus pages or even some obscure languages, and why I still haven’t has several reasons:
I don’t know how to go about adding stuff to Exercism. I looked at /contributing, it’s more about fixing what’s there than adding.
I don’t know what is actually needed. Does Exercism need more languages? More exercises? More learning tracks and syllabi? Would Exercism prefer to improve on what’s already there before adding more new things? I poked around /contributing and saw items I could check out, but they are not new languages or new learning tracks.
