Should I use Javascript?

Use it in a non-obstrusive way, and make sure it has no negative impact for users that have it disabled. Those who have it enabled will see a little extra and those who don't won't even notice anything wrong if it degrades nicely.

This is a nice thought, but if you are building an ajax powered site, not really viable. I'm currently working on a site that has a lot of different tabbed modules, all grabbing data from the server, this fails without JS turned on.

I'm all for use JS to add functionality, but in some cases, JS is needed just to make the site usable.
