You're talking about the material of the Twitter discussions where I'm more discussing the article itself, which is about the community and discourse surrounding it.

If you want my opinion on that, Odin seems pretty notable to me, and I would expect there to be a Wikipedia article for it, and I'd be all for engaging with the editors on that. I wouldn't expect Wikipedia moderators to be plugged into the world of programming languages the way I am, though. Like the article says, this seems like subject-specific notability guidelines could help. It's definitely true that the programming world is missing the kind of institutional material that works well for, say, science or news.
