Media Queries and Fold
I like how Paul Boag thinks about using Media Queries to design better and overcome the limitations of the fold.
Having a technique like this at our disposal means that we can avoid a lot of the awkward conversations with the client where we try to explain how the fold does not really exist. It also enables us to have more freedom with our layouts and use of whitespace without being concerned over whether key messages will be missed at lower resolutions. In short it takes the sting out of the fold debate.
