the separation of content and presentation has been important in web design from a code perspective. CSS exists because separating content and presentation was desirable. But most people don't want to deal with all that mess. They want to make a fun web page quickly and easily to serve whatever purpose they have in mind right then.
I'm not talking about CSS, I'm talking about removing the content from HTML and sticking it in a database. Thus HTML is merely a template to be reused over and over. Hence boring layouts that work with all content equally well. In some situations this is critical, I'm not arguing against its existence, but we've gone too far in that direction whereas, as this article points out, there's not a lot of tailored web pages on the internet any more. Which is a shame.
