I run NoScript in Firefox and only sites I've specified have JavaScript enabled, and usually only for files served by that domain.
So I guess I'd count as someone with JavaScript disabled for the vast majority of sites where I am just reading something and not wanting to interact with the page.
I use Chrome's built-in javascript blocking. It's simple and gets the job done. Best of all, my whitelist is synced across all my Chrome instances, including fresh installs.
