There is not one site for the best viral videos. There are so many sites around all with really good videos on them. However due to the huge number of videos on site like video.google.com and youtube etc they all become a bit of a pain to search. Thats why I prefer following a couple of weblogs which actively hunt for these type of videos which means I don't have to

differentiating between youtube and googlevideo is oing to become more problematic, seeing as both are owned by google...
