Case Studies

There is one example in the **Elm-Specific Articles** section
```
How Elm made our work better (success story): http://futurice.com/blog/elm-in-the-real-world
```
I'd love to see more success stories or case studies of where Elm is used over traditional JavaScript Web Applications

Review the Elm-Specific Articles section and the existing Futurice success-story link in the issue. Identify additional documented examples of Elm use in web applications, then add the selected case studies to that section; done means the learning material contains more relevant success stories.
