Do you really need JavaScript?

My default is to browse with NoScript actively disabling most JS. I'm happy with at least 90% of my website interactions.

Here's the full extent of my permanently whitelisted websites:

   apple.com
   cdn-apple.com
   edmunds-media.com
   edmunds.com
   newegg.com
   wikimedia.org
   wikipedia.org
   yahoo.com
   ycombinator.com
   yimg.com

In addition, selectively doing View->Page Style->No Style often displays content that would otherwise require JS.

For most of the rest I just say Fuck It and move on to something else. There are plenty of other sites out there, and life is too short.
