This reminds moe of Joe Davis' Telescopic Text: http://www.telescopictext.com/. Assuming you see this on a desktop computer, it's exactly the opposite of Frankie's responsive text: instead of gradually reducing the amount of information, it gradually increases it.

That's really clever. I would like to read news articles written like this: you just click on the parts you want elaborate on.

Not only would it be more convenient for you, to focus on bits of the story you're actually interested in, the newspaper could collect analytics on what parts of the story you're interested in, and suggest further articles, and highly-targeted ads, based on that.

Imagine you see an article about Christopher Hitchens accusing Henry Kissinger of war crimes, and Kissinger is wearing a smart suit, and you dive in to find out more about his couturier. The click-through rates on high-end clothing ads would be vastly more.

Though, to take the opposite tack: would this encourage newspapers to turn into something like mesothelioma blogspam? Writing about something, only because the ads associated with it are profitable, instead of because it's a Fact Worth Knowing?

It might also be a really bad idea because you constantly force people to make conscious decisions about which parts they want you to elaborate.
