Given all of the discussion last month around social media analysis, I thought my latest piece might be of considerable interest, tracing the evolution of Twitter 2012-2018 through the 1% stream, charting everything from its growth to its retweet and linking trends, to its changing geography. There are a lot of statistics in there of considerable relevance for those studying Twitter and social media more broadly: https://www.forbes.com/sites/kalevleetaru/2019/03/04/visualizing-seven-years... It essentially repeats the analyses of my previous 2012 and 2015 studies, this time with a much longer time horizon, updating a number of the statistics and charting how they have changed over time: https://firstmonday.org/article/view/4366/3654 https://www.theatlantic.com/international/archive/2015/08/twitter-global-soc... The transition of Twitter from a content platform to a behavioral platform via its centralization around elite accounts and the rising retweet density have particular algorithmic and methodological implications for Twitter studies.
