Elm as a language is really nice, and I do like the goals of the project. I tried it out a bit, its a mind-bending paradigm for someone coming from OOP/prototype (Python, Java, JS) and I enjoyed the challenge.
I hope things work out well for you in this project with Elm, now and in the future. But it doesn't seem like any of the issues with the community have been even attempted at being addressed, so I don't think I will give Elm another try.
The community, on the other hand, is what turned me off. It does seem very unfriendly to newcomers. In addition, https://lukeplant.me.uk/blog/posts/why-im-leaving-elm/ amongst others, is an entire turnoff. And seems like this perception isn't isolated and has been discussed at https://news.ycombinator.com/item?id=22821447
