The random character situation is a false comparison since that is not the case here. It is a useful model of the situation, you have 50 (lets say) decisions to make (border color, margin height, number of images per row, ...), each with 5 (lets say) equally likely outcomes (#666 is quite as good and popular as #777,#888,#555,#444; 1.0em like 1.5 em,0.5em,2.0em,2.5em; ...). All I'm saying is that you cannot explain that many visual and conceptual solutions being the same with chance alone, since that is an event with very low probability if you honestly perform each decision by yourself.
