In what sense does this prove that they are receiving quite a bit of traffic? I see one article, http://digg.com/linux_unix/Ubuntu_9_10_Karmic_Koala_released got 1512 users, which means we have proved that digg.com got at least 1512 unique users. Granted, that this is not a fixed voting system of course. Secondly, how do I quantify 'quite a bit'? I think we can settle to say that you got no proof nor documentation that shows us the amount of traffic that digg actually got.
