Also, not being able to rearrange blocks for different size displays is kind of a non-starter relative to the mobile internet, which I'd guess was more important than frameworks.

In my own hobbyist stuff, though, there's just something a little gross about putting layout in the HTML -- I want HTML to represent semantic structure, in ways I'd be okay with Lynx displaying, and I want CSS to do all the lunatic nonsense to make me happy with how it looks on a modern browser. I wonder how much it's this aesthetic principle of separation that motivates others as well.
