Sorry, I didn't mean to sound grumpy. I just wanted to say that as a C#, Python and Javascript developer, I am put off by the arguments put forward in the landing page.
Saying that is as forgiving as Javascript, as productive as Python and as robust as C# is a better way to sell the language than saying it is C# minus typing, Python minus easy syntax and Javascript minus problems...
Notice that the author was rather effective at getting us to think about the features of these languages and how crayon fits in.
