Relationship Economics uploaded the PDF of the research paper submitted to The Journal of Consumer Research. That was useful for drilling down to see what it says.
It pulled some quotes from a Science News article on the research, too. Those are not useful, in that they tell us things like to make viral marketing work, "make it a good idea" or "be remarkable" Duh.
Good, remarkable ideas typically are the hard part. A New York Observer article, Beloved Esquire Franchise, 'Dubious Achievements,' Becomes One, noted that the people who worked on Esquire's annual Dubious Achievements issue (may it rest in peace) did so because they were passionate about the project, and would spend months crafting the items. They might spend three hours to get six jokes, five of which would be rejected by the project's head. They did this kind of work every day for perhaps two or three months.
That is how you get the kind of remarkable ideas that will influence the influencers, and wow the influenced. Though, as we saw with Esquire, you can be so influential that you get copied out of existence.
