Twitter users with anti-vaccine opinions are relatively easy to spot if we can measure their misinformation exposure

Of course Europe is very interesting with the clear borders and the unusually high density of tweets in the Netherlands - … Continue reading Language communities – another use for Twitter

“Sipping from the fire hose” – sampling Twitter streams
