> I'd much rather that a site just give me a long list of results, and allow me to scroll through them without loading delays.

I think that is a balance between server load and user convenience.

On ddg it is already pretty fast, if you aren't in a real hurry it is hardly noticeable and faster than clicking through to a second page.

Well, that, and the fact that users really hate pages that are slow to load. (Although most of the loading would happen off-screen, this can still slow down users/other requests/...)
