With all respect - the opposite is true. The web succeeded because HTML and HTTP are easy standards easily writable by humans with text editors. HTML was writable by non-programmers.
That's not obviously so. The adoption of JS wasn't particularly hindered by the fact that users have to match their brackets and generally avoid syntax errors.
I don't think "parsed strictly" makes something hard; on the contrary, I think it's helpful to make something easy. Clear feedback, easy to test.
But then, I've always preferred strongly typed over stringly typed.
