I think there are an incredible number of technical challenges for web applications that are more interesting and important than consistency (focus of article). How about scaling on the backend, performance on the frontend, reliability, security, having a sufficiently rich browser platform... I'm sure this list could go on for hours. I don't do much frontend web programming, but is it really the case that no framework is providing native look-and-feel via js/flash/etc? I mean, Java has been doing this for a while and it is certainly not the new hotness. Chrome (among many others) also allows web apps to snap out of the browser and appear as a desktop app to OS GUIs. Confused as to what the big problem is.
