Please! javascript is an essential component of every modern web site. If you want to live in a cave and think that flickering shadow on the wall is all there is to the world then fine, but not all of us are imprisoned by progress.
Sorry, I use a browser which trivially allows me to only enable executable content for sites I trust and until you're one of them no javascript for you.
Your preferences are your business, but just because you don't run javascript doesn't mean a site is broken. It means you have a default setting that is in conflict with the current state, and direction of the web.
If I do:
csh> lynx www.facebook.com [et al.]
it really doens't mean facebook is broken.
That's my point - you're mixing up your personal preferences (paranoia) with the condition of a web site and they are not the same thing.
Fortunately many others are willing to move with the times, otherwise we'd all be still running gopher://news.ycombinator.com
If your site requires JS, not bothering to tell people just shows how much you (don't) care about your users. It's interesting you bring up facebook. I'm not a facebook user, but on I whim I just went there and what's the first thing they told me:
Sign Up
It's free and anyone can join
Javascript is disabled on your browser.
Please enable JavaScript on your browser or
upgrade to a Javascript-capable browser to
register for Facebook.
That tells me that the people at FB care enough about my time and theirs to tell me their requirements before I use the site.
Still, it's really easy to have a "this site requires Javascript" message. It also demonstrates a minimal level of design diligence. (It's a little like ensuring labels work to toggle checkboxes, or not using fixed-size fonts, and so on.)
