#JavaScript should be off-by-default and enabled on a per-site basis ... and only if necessary for some particular site function.

I just visited http://diveintomark.org/ just to see whether Mr. Pilgrim decided to come back one more time. Instead, I see one of those "this site works better with JS enabled" messages. Being me, I CTRL+U and view source. Yep, just as expected. Adsense.js ... I didn't read farther, so I don't know whether this is one of those squatters.

Nope. Not going to turn on JS.
