Great to hear you'd consider using it. If when building the app you find yourself wanting to contribute to the js parser[1] in any way (or even any non javascript-based parser), it'd be much appreciated. That's my biggest need right now, is actually writing a good parser that'll encourage people to try this out.

And fair, re: "you wouldn’t build a web app in markdown". I'm sure it's been done :)
