[O]ne more reason for being judicious in the use of JavaScript - I am predicting that within 3 years 35%+ of all "web" traffic here on campus will be consumed by mobile/hand-held devices, so I for one am watching this issue carefully.
John Foliot wrote a very thorough email to the W3C-WAI-IG ML (Web Accessiblity Initiative Interest Group mailing list) a few months ago, and I should have pointed to it here much earlier. His point is that while from a desktop browser point of view the problem of Javascript looks like it’s kind of solved, the can of worms is reopening again with the emergence of the mobile web.
