I agree that you should know your target audience, but I think it's also a cost-benefit issue. I'm all for making your page accessible to as many people as possible, but in many cases it's not practical to cater to the 3 hits per month that for some reason still use Netscape 4.x.
I disagree with the article that you might need to "dig out some old favorites like @import" for older browsers. As discussed in "To Hell With Bad Browsers" ( http://www.alistapart.com/articles/tohell ), you shouldn't have to deal with people who refuse to use a modern browser. (Hmm that was 6 years ago now... am I old?)
I agree with the article that it's illogical to load an entire page with AJAX and not have a non-javascript option, but I think the whole 3-level scheme is overkill in some cases. I think it comes back to knowing your audience, and designing your site so that they will be able to use it how they want.
