Slight hyperbole, but I understand what you mean. Assuming OP has never succeeded in creating a truly viral video then a pontificating title such as this is sure to get a few backs up at the very the least, certainly amongst hypersensitive and hypercritical HN commenters.
Having never made one myself, I can only imagine that making a viral video is largely a function of luck, so any treatise on how to make one might just be viewed as a hypothesis that provides something useful when one synthesises their own strategy. That's how I looked at it, and that's why I'm grateful for the OP having shared it, rather than getting insanely worked up behind a computer screen.
It's not that it's luck behind viral videas, it's that they tend to spread or become popular in their own unique ways and attempts to deduce general rules from examples you had nothing to do with is usually foolhardy.
There is some science behind virality and for that I'd recommend looking at Jonah Berger

Thanks OP.
