In case anyone feels like complaining about Persona depending on JavaScript: yes, it is true that it depends on JavaScript at present, but that JavaScript is only a crutch—a polyfill for something which is intended to undergo standardisation and formalisation as core browser functionality. Assuming that happens, Persona-based sites will thus in the end not depend on JavaScript.
I don't think his point was that client-side scripting is bad, just that there is way too much of it and the way some people use it change fundamental functionality.
"that JavaScript is only a crutch—a polyfill for something which is intended to undergo standardisation and formalisation as core browser functionality."
Thats excellent. However if the poster requires behaviour that's built into the browser, he may as well require behaviour that's supplied by the site.
