I'm not saying that Erlang shouldn't reach out to new users. I'm saying that new users should look past the website and put in a little effort to know about Erlang. Dismissing a language because of the its website is not just right.
This is a list of compile-to-javascript languages: https://github.com/jashkenas/coffee-script/wiki/List-of-lang...
Is any developer going to give every language on that list the same consideration?
No. Not possible.
