For those unfamiliar with elm:

I would sum it up as:

-) a stripped down, simplified version of Haskell

-) with a good concept for side effects

-) that compiles to Javascript

-) gearded towards writing type safe frontend code for the Browser

-) strongly nudging you towards a clean, well architected app structure (see 'the Elm Architecture').

I think it's on the tipping point right now:

if enough people jump on board, the language get's good documentation, and the library ecosystem grows, I see a great future for Elm.

Otherwise, it will dwindle away soon into the endless annals of forgotten languages.
