It really depends on your audience. As a general rule, you should try to make your site allowable for javascript-disabled-noobs to still be able to go through the primary functions of your site. With that said, out of our 1m visitors a week, we have less than 0.1% with it disabled. So it's a tradeoff - how long will it take you to code the extra to allow those 0.1%, and does this require extra code and junk up. We don't support any browsers once it gets to below 1% - aka IE7 so I don't generally go out of my way to make sure everything works for non-javascript users. It used to be more important back in the day with the old school mobile browsers etc with the good ol' WAP (as Jonnie says)
