Twitter Follow Graph, August 2009 (MPI-SWS, ICWSM 2010) Analyzed
The follow graph of Twitter shared by the Max Planck Institute for Software Systems (MPI-SWS) for the study "Measuring User Influence in Twitter: The Million Follower Fallacy" (ICWSM 2010): 1,963,263,821 directed follow links among 52,579,682 accounts, with account IDs anonymised, so the file carries structure only, and a table of the number of new adopters per day of seven retweeting conventions (RT, via, Retweeting, Retweet, HT, R/T and the recycling symbol) over 883 days. 43,983,853 accounts follow at least one account and 49,395,940 are followed by at least one. The page that publishes the data says it is based on the Twitter network snapshot of September 2009 and that the tweet information is not shared.
