Only testing specific examples is not enough. Without testing against a theory you gain little knowledge from these experiments. I would like to see reports of people testing their beliefs about how web design decisions affect user behaviour instead of finding out which design works better for a given site. Of course this is more time consuming but it will also yield more valuable insight. Also I think it is important to include feedback from actual users in your test results. How did they feel using the different sites? What are the users feelings about your own concerns (invisible content below the fold, ridiculous big buttons, etc)? Without these considerations you are just poking around the mud with a stick.
