Not sure I quite understood his rant either, except perhaps he probably has no idea how a browser should behave or be able to accomplish certain aspects of development without it... Progressive enhancement is not difficult. Just build your site as if there was no Javascript and then add the JS bits. Easy. With all the js libraries about it's even easier these days, use something like yepnope.js and it'll even allow you to load scripts based on what capabilities the browser supports. Progressive enhancements becomes difficult when it's an after thought, maybe when you going into testing and suddenly realise the developer hasn't completely read the specs! I totally understand for some sites it is completely necessary, but for sites like Twitter and Facebook it should not be necessary. Sure the JS adds a gloss and finish to make the user experience slicker, but there is nothing on there which could not be achieved with plain old html and css... Also, for some of us we still have to support sites with JS turned off and even (unfortunately) support IE6! It's the requirement of the client and although most likely none of their customers will have JS turned off or run IE6, the corporate big wigs in head office will need to give final approval!
