> I'm sure there's some way I could use Haskell or OCaml to write Android and web apps.
I don't know about Android, but for Javascript apps the balance tipped for me just last month. I'm probably enough of an insider that it's not quite true yet for the average Haskell developer, but I believe that will change soon.
What framework are you using? I've investigated Dart, Flow and TypeScript to improve static checking but I'm still having pain points: they work fine when dealing with your own self-contained code but integrating with third party libraries isn't always straightforward.
I'm using GHCJS and Reflex. Reflex is a recently released FRP library that makes a huge difference in one's ability to abstract GUI code. I personally feel that this combination of GHCJS + Reflex is the first thing I've used that makes web front end programming tolerable. A week ago there was a presentation about it at the NY Haskell Meetup. Look for videos of it to be posted early next week.
It's new, so not right now. But docs are coming. The NYHUG presentation will probably be the first thing along those lines. My company just rewrote a significant front-end app in it, so we clearly are invested in its future. In the meantime there's a #reflex-frp IRC channel on Freenode that you could use to talk to some of the people currently working with it.
