There is a fair question here (though presented with questionable integrity) about what notability means in programming languages. Especially for more recent and perhaps not widely used programming languages.
I have a particular interest in programming language design and, for what it's worth, I have heard of Odin. For someone like me, understanding different design decisions for languages that depart from mainstream languages is valuable. It isn't what academic journals are interested in and there are no notable publications for hobbyists or language design experts (that I know of).
Notability *is* worth questioning for a field like this since there isn't a clear signal outside of blog posts and user community discussion. There's no clear place where general discussions around program languages is happening to a reasonable level of depth and quality.
On that note - @dang I would love it if https://news.ycombinator.com/showlang continued to update. It was a cool resource for finding discussion on new programming language designs here on HN.
