title: Is it reasonable to use John Resig's Processing.js?
body: <p>I am thinking about making a website with some fairly intense JavaScript/canvas usage and I have been looking at <a href="http://ejohn.org/blog/processingjs/" rel="nofollow noreferrer">Processing.js</a> and it seems to me that it would make manipulating the canvas significantly easier.  Does anyone know any reasons why I <strong>shouldn't</strong> use Processing.js?  I understand that older browsers won't be able to use it, but for now that's ok.</p>
