> Nice piece of work. The role of influencers in this study is akin to that of hubs in scale-free network. Diffusion on scale-free and small-world network have been studied extensively in physics community. It will be interesting to compare the results from this paper with work on scale-free networks. Also, context is everything. A social graph is not a flat structure. This work, for instance, https://arxiv.org/abs/1507.03826, shows that how consensus is formed and spreads across an agent population depends heavily on how different network types overlap. I also remembered this work on how…

Here's a recent follow-up paper [1] testing exactly that on many diverse datasets, positing that scale-free (power-law distributed) networks are actually not that common in the real world. Quanta has a nice article about it [2]. [1] https://arxiv.org/abs/1801.03400 [2] https://www.quantamagazine.org/scant-evidence-of-power-laws-...

Power laws and scale-free networks are discussed in https://arxiv.org/abs/1801.03400 with HN comments at https://news.ycombinator.com/item?id=16144867. Both this and the cited paper are worthwhile reads for power law users.

A central claim in modern network science is that real-world networks are typically "scale free," meaning that the fraction of nodes with degree k follows a power law, decaying like k−α, often with 2<α<3. However, empirical evidence for this belief derives from a relatively small number of real-world networks. We test the universality of scale-free structure by applying state-of-the-art statistical tools to a large corpus of nearly 1000 network data sets drawn from social, biological, technological, and informational sources. We fit the power-law model to each degree distribution, test its…
