Suggestion: you really need "here's what the syntax looks like" example(s) on your home page with some non-trivial code (more than just hello world). Ideally, show the sample and the JS output side by side like on the CoffeeScript home page: http://coffeescript.org/
I suppose I am being a bit of a blushing bride about the syntax as it isn't mine, just being good old-fashioned Erlang.
The demo doesn't show much more than hello world, because that's all there is at the moment - the focus has been on building the end-to-end toolchain and I am now filling out the features, but good suggestion going forward.
I read "OTP-ish dialect of Erlang" as meaning it's not quite the same, and I was looking for details of those differences. If it's just plain Erlang, then I see your point.
