Many of those people should not be building applications. Boilerplate startup landing pages, blogging platforms and e-commerce sites should be websites, as they always were.

As for those who really are building web applications - well, those are separate beasts. Nobody expects to run Google Docs or Gliffy properly in lynx. But I do expect my banking site to run in a text browser, because there's no valid reason it shouldn't.

(Yes, I understand the business reasons for the current sad state of the web. I also believe those reasons are things one should be ashamed of.)
