Assuming that you're talking about Richard Feldman, he shows up regularly but not to talk about Elm—Roc is his new project, which is inspired by Elm but not trying to target the same niche.
I kind of wish the effort spent on Roc was put into productionizing/commercializing Koka (which Roc draws a lot of inspiration from) rather than starting an entirely new language. Like I get starting from scratch when it comes to Haskell, since there’s so much baggage there, but Koka is a pretty blank slate.
Koka is still pretty much one person's project [0], and it's not for lack of PRs [1]. To push Koka forward at the kind of pace that Richard wants to move would require forking it or commandeering it, and it makes total sense that neither option is as appealing as just starting fresh.
He’s the author of the article but only chimes in once.
Sorry for not linking it, just wasn’t sure I wanted a Google Alert, but it seems likely at this point and I don’t mind. I’m somewhat undecided about Elm and Roc. Both are at least innovative.
A Google Alert notifies when a search term, such as someone's name, appears online, so mentioning someone in a public comment might trigger an alert, causing them to notice it.
Now I understand, the author is (or was, I suppose) a core team member of Elm, I thought it were someone that commented on the post instead. I interpret "showed up on HN" to typically mean a commenter rather than an article author as typically many authors don't even realize their article was submitted to HN on any particular day.
