As someone who's a recent convert to the language, I have started making several webapps with Elm lately. The biggest thing the language lacks right now IMO is solid tutorials for some concepts. I was able to make my way through but due to the young age in the language tutorials are sparse and widely varied in their effectiveness. In terms of learning the language, the error messages were a godsend. Now that I am more comfortable with the language overall (which only took a few weeks of intermittent learning), I have joined the Elm slack channel.

I can say now that the Elm community is VERY responsive to current devs, and Elm's development is not just focused on new people, but that is where the blog posts and updates focus because, frankly, it's a new concept that Elm is focusing on that many languages do not currently, so it bears mentioning and makes for better updates than normal esoteric patch notes would (which any power user CAN still find).
