Can maths predict the rise (and fall) of Facebook?

A couple of Princeton researchers however believe that their mathematical model may do a better job at predicting the health of a social network than some of the aforementioned soothsayers. What’s more, they believe they’ve discovered that the fate of Facebook is not looking so good.
Based on the rise and fall of MySpace, John Cannarella and Joshua Spechler say that Facebook, the largest online social network in history, is set for a massive fall.
“Ideas, like diseases, have been shown to spread infectiously between people before eventually dying out, and have been successfully described with epidemiological models,” they wrote.
To arrive at their hypothesis, they applied a modified epidemiological model to map the user activity on various social networks. They used publicly available Google data for the research, and believe that it shows that Facebook is set for a substantial drop in usage.
“Facebook is expected to undergo rapid decline in the upcoming years, shrinking to 20 percent of its maximum size by December 2014,” said the report posted online to peers at ArXiv.org.
“Extrapolating the best ?t model into the future suggests that Facebook will undergo a rapid decline in the coming years, losing 80 percent of its peak user base between 2015 and 2017.”
It’s quite a claim. Suffice to say, the paper has yet to be peer reviewed so it seems unlikely that Mark Zuckerberg will be too concerned, and the likelihood of such a dramatic drop in usage seems unlikely.
The underlying principle of mapping human behaviour to that of a virus however is an interesting one. There have been numerous attempts to predict the spread of ideas and content in a viral manner, most of which have failed to do so consistently. It will be quite a coup if the two academics have managed to pull off a similar trick in this instance. We’ll just have to wait and see what December brings.Original post
