I think it depends on what the JavaScript is used for. I agree that blogs and news site should be static, but forums - and in general, sites with a high degree of user interactivity - can see significant UX improvements with some JavaScript, for things like asynchronous loading, changing the UI without reloading the page, and even nice animations (although many of those can be done in CSS these days). However, graceful degradation is very important - disabliing JavaScript on these sites shouldn't break them, merely impact the UX.

[Edit] "blogs and news sites should be static" -> this should read "blogs and news sites don't need JavaScript"

Agreed, enhancements are good (and often nice on a modern devices with all the bells and whistles enabled), so long as it degrades nicely.
