I had posted a comment on that there iceberrrrg site regarding how I believe his analysis and 37signal example was incorrect.  Low and behold my comment did not get approved.<p>I'm still sticking to my guns that 37signals heavily implemented tactics for optimizing click-throughs and conversion ratios based on their bread and butter services being listed with bright and bold colors ABOVE THE FOLD.<p>On that note, it's slightly disheartening that this article is generating such attention on HN.
