The problem is that once javascript is enabled on a page, there is too large of a business incentive to tack on google analytics, auto-playing video ads, facebook and linked-in and twitter integration, annoying subscribe popups, etc. Javascript is necessary in the web that I want for the future but I want some standards for what gets run in my browser without me going through manually and whitelisting specific scripts to block out the 10s of MB of crap that get thrown at me every time I go to a new site.
