This finding may have implications when it comes to studying the information flow of social networks, marketing and web design.

Wondering also..... could this change ad placement for revenue models? If an ad gets a click on a story older than 36 hours, is it worth more, less?

Could be some interesting algos written to determine this sort of thing and may even lead to expiring ads, or publishers requesting only "fresh" ads from news sources.
