I'm not saying it's the be-all-and-end-all at all, there are lots of design problems. But arguing UX design with someone who believes sites shouldn't be using JS? It's just not a credible position.
Simple web pages are not simple. What makes them simple is that the complexity is hidden. JS is a major part of hiding that complexity, whether it's for preloading data, "don't make me click", or just hiding away things you don't need yet.
The search is a great example: I suspect almost nobody uses search, and I also suspect that those who use search use it a great deal. I suspect that Lifehacker has those "where do people click" charts that show them that information, and that as a result they made it powerful, but decided against giving it a whole bar.
Likewise comments. They hid away most of the commenting chrome because 99% of people dont comment, and they want to engage them with the existing comments.
There is no such thing as "a simple web page with some content". It is naive to think that it is, and I believe (please correct me if I'm wrong) that it shows that you have not spent significant time working on web UX issues in a cross-browser environment.
Don't forget that LifeHacker is part of Gawker. There's about a dozen sites in that network, probably all using the same codebase. What proportion of Jezebel readers do you think use NoScript?
Really? I guess you are right that this conversation is over. I'm sorry, but Lifehacker is not the end-all-be-all design mecca of the 21st century, quite the contrary, in fact. I only picked on the Javascript issue -- there are plenty more issues to discuss if you want to discuss design.
It's not about 2% of the population who don't use Javascript. It's about the fact that they're doing something fundamentally wrong if they require Javascript for displaying a simple web page with some content.
