In our paper Stigmergic Epistemology, Stigmergic Cognition we noted the phenomenon whereby swarm behavior runs the risk of a dysfunctional communal narrowing of attention that can be self-fulfilling. This phenomenon is validated by Jonathan Touboul in his revised paper freely available here. As Touboul rightly says, this phenomenon is found across all domains of collective intentionality but it is especially noticeable within the domain of the socially “fashionable”, hipsters hardly being unique in this regard. The so-called “fashionable” set(s) should not be conflated with a classic aesthetic.
