Twitter under the microscope, from HP labs – even when using a very weak definition of “friend” (i.e., anyone who a user has
directed a post to at least twice) we find that Twitter users have a very small number of
friends compared to the number of followers and followees they declare. This implies the
existence of two different networks: a very dense one made up of followers and followees, and
a sparser and simpler network of actual friends.
