Relationship between number of PubMed citations and number of CiteULike posts per citation plotted on a log-log scale. The X coordinates of each point on the plot correspond to the Log of the number of different people to post a particular citation. The Y coordinates are the Log of the counts of the number citations that occur in each of the bins provided by the number of posts. The near linearity chart illustrates the exponential relationship between the number of citations and the number of CiteULike users to post a citation -- a few citations are posted by many people but most are only posted by a few.
