at least in this case one of the ideas seemed to be that if they did an ajax load of the middle section of the page, they could skip sending the fixed elements (header and footer) over the network repeatedly
To be fair, an iframe would accomplish that too, but the loaded content would have its own html header that adds to the amount of kilobytes used. So maybe that's the reason.
