If you disable JavaScript, I'm afraid you're not the target audience of 99.99% of the commercial/content internet. The web is no longer static, and websites are now essentially applications. This is a generalisation, but it mostly holds true I think.

As for bookmarking - any dynamic single page content site and many applications will support linking directly to a certain content or section of the app via various techniques.

JavaScript is not a nice enhancement. It IS the web.

It's fine to think of JavaScript as something that you depend on for major features but I still think you have to follow progressive enhancement. A small, but potentially growing, number of users have JavaScript disabled completely but a much larger number of people effectively have it disabled for a non-trivial period of time while things download or even, due to errors, until they reload the page.

If you don't degrade well under those circumstances you're at a competitive disadvantage to sites which do something like quickly return a core HTML page which can display immediately while the full app loads.
