This only makes sense to me in a progressive loading situation. That is, you load the summaries first, then load additional detail later in the rendering timeline. Fine; I'd get that.
But I don't like the idea of not getting the full story every time. Why not think a couple years out and assume everyone's connection is fast enough to handle text - LOTS of text - even over a mobile connection. It's text. Like one-or-two-bytes-per-character stuff.
I suppose it's also interesting as a navigational scheme. To show summaries automatically and expand on some user action, a la clear (http://www.realmacsoftware.com/clear/).
