http://images1.bingocardcreator.com/blog-images/hn/no-fold-h...Caption for the PNG impaired: it is a heatmap pulled from my site, which shows interaction above the fold being absurdly more likely to happen than interaction below the fold, even for elements which are not actually clickable.  (You can't tell but more folks click the "New Card" button on my screenshot, presumably expecting it to result in a "New Card", than click the below the fold calls to action.)Strictly speaking it would be more impressive if I created two designs, one with an aesthetically pleasing design and the call to action below the fold and one with the same design but the call to action above the fold, then A/B tested them against each other.  I'll do that when some talented designer pays me for the damage it would do to my business.Sorry guys, art warms my heart but math pays the bills.
