Ever notice that YouTube videos are often dugg by association?

What do I mean:

These three videos are the first, sixth, and twelfth top stories on digg today, and guess what? They are all right next to eachother. Unless there is another way to explain this then it seems like its not always the best YouTube videos that get dugg but just the interesting ones surrounding other videos.  This is not necessarily a bad thing, but interesting none the less.
