It seems to offer a learnt summary of the relevance of network science (which offers a complementary perspective on the phenomenon to the microeconomic literature linked by other commenters), which not implausibly took Jan at least an order of magnitude less time to compile than it would have taken us. (For example, the seemingly simple fact of using a different Google scholar keyword than “information cascade” might have taken several hours to realise for a non-expert.)
It also attempts to apply these to the case of forecasting (despite Jan’s limited knowledge of the domain), which is a task that would likely have been even harder to do without deep experience of the field.
We (jacobjacob and Ben Pace) decided to award $200 (out of the total bounty of $800) to this answer (and the additional comment below).

I’ll PM Jan about payment details.
