So does he think there should just be less content? It's one thing for a blog (e.g. daring fireball) to have a sweet minimalistic design that only shows you one thing at a time... but sites like Amazon and the NYTimes have an absolutely massive amount of content that they're trying to provide. How is the NYTimes supposed to make a sleek, un-cluttered interface when they have 3000 new articles every day? And it's not junk -- nearly every one of those articles is thoughtful and well-written. They all deserve some attention.
Do you have any examples of websites that have ginormous amounts of content and simple, un-cluttered interfaces? And don't say google, because that's different.
