An Ethnography of Wikipedia" with Stanford University Press), collaborative society (2020, "Collaborative Society", MIT Press, co-author A. Przegalinska), a phenomenon of technology radically enhancing a natural trend of people to cooperate, visible in peer-to-peer production, uberization, online cooperatives, but also in meme culture, and better explaining the emerging change than the buzzword "sharing economy".
More recently, he studies how people create systems of ignorance and antiscience (2027, "Antiscience", Routledge) and disinformation (2027, "Disinformation and Misinformation, co-author J.

He also is a co-founder and CEO of InstaLing, a free platform supporting language teachers currently used by over 200k people.
Recently, he also co-founded RunPixie, a startup for runners, offering community-sourced pictures from mass races, recognized by AI. As a hobby, he developed Verbatio, an app that helps you learn a foreign language by reading books, PDFs, websites, looking up words in large dictionary databases, and memorizing them through flashcards: https://verbatio.app He serves on the council for the Ignoble Prize (for research that makes you laugh and then think) and, in general, thinks that academia should not be overly serious. A while ago he discovered that Godwin's Law (rule of Nazi analogies) does not work on the internet and that intercessory rote prayer does not increase longevity.
