Hi Kate. Fascinating article, and thank you very much.
One very minor quibble — your write-up implies at one point that the ‘guardian.co.uk’ domain is a fake news node: “The domain is owned and operated by Patrick Henningsen, a journalist who has worked for RT news, Guardian.co.uk, GlobalResearch.ca, and Infowars.com. Perhaps not surprisingly, all of these domains are nodes in our graph.”
This seems a little unfair and inaccurate: The Guardian is a mainstream (albeit fairly left-of-centre) UK newspaper, and is no more ‘fake news’ than, say ‘The New York Times’ or ‘Washington Post’ are.
