While I understand your point, I disagree with the conclusion. Simply because a system is complicated that doesnt mean that we should give up. You create a first order approximation and then iterate (very much like how it seems dmor is trying to do). If you know something about how the Alexa ranking system works that we do not, then by all means share it. Simply saying that the author does not know and therefore all conclusions are useless is unhelpful and probably incorrect. To be honest, this reminds me of the elderly who dont understand computers and just give up without trying.
