Not stressing too much the above-the-fold concept does not mean there is no difference between up and down the conceptual line of the average screen height resolution of your visitors. You can use the content that has no need to scroll to capture the attention, but there is no need to stuff everything there. I think that 37 signals is an example about that as they don't try to put too many "information" above the fold, but only a few important stuff, and many other info is distributed across all the page.
