Nicely executed, the video is well done. Will be interesting to see if real-life examples of viral content come out of this kid of model.
IMHO, users need to choose to share content themselves in order to go viral : it's not the link-posting (which is the basis of all twitter spam) that produces the virality, but the passion and wording of the people describing the content AFTER they've seen it that gets their friends to check it out.
Unrelated question : how does an article with 0 comments get to the top of HN ? :) Would love insight into the HN algorithm on this one.
