It's widely agreed that some SE won't follow links using JS, so I use HTML from the index page to all sections of the site. But I do also use a JS dropdown navagation from those second level pages, in addition to HTML links. Also I rely heavily on optional JS pop-ups to add additional info relating to page subject matter.
And what would be the point of disabling browser JS anyway?

As with just about everything else, this seems to vary greatly with the type of audience. Tedster posted a great set of stats a few days ago that show 89% of the web users are js-enabled, up from 80% just a year ago. I deal in general interest sites likely to be accessed by the average JohnQ with whatever browser defaults he happens to have when he opens the box. I guesstimate that 93-95% of my visitors have js.
I find that most visitors do have JS enabled (80-90%), but you should still use it carefully. Visitors using assisitive technologies - screen readers especially - may have problems if a lot of your page is JS-driven.
They may not be able to access the information. Also, if you use a lot of JS menus, be sure to also include text links for those people using keyboard navigation.
This makes your site more accessible to people with disabilities AND people using PDA's and other new technologies.
