Updated: 2018-Jul-13 02:34 UTC. Listed users: 466. A feed's listed count is the number of Twitter users' lists on which the feed appears. A feed's rank spread is its rank by listed count minus its rank by peer followers; feeds ranking better per peers than per the public will have larger positive values, while those ranking better per the public than per peers will have larger negative values. The composite metric is the quadratic mean of the rank by listed count and the rank by peer followers. This list is ordered by the composite metric. For a list ordered by followers and including listed counts, see Philosophers on Twitter. For a list ordered by peer followers, see Philosophers' Favorite Twitter Feeds. Feedback: @TrueSciPhi.
