Out of the approximately 1,100 planning faculty that I track, just over 300 have active Twitter accounts (about 100 users for each rank). Similar to my comparison of Google Scholar users and non-users (see: http://tomwsanchez.com/the-google-scholar-citation-profile-advantage/), I was interested in whether citation activity differs between Twitter users and non-users. Below are some initial results from this research which show there are differences between the two groups, with Twitter users having higher numbers of total citations as well as H-Indices.
Your comments are appreciated.
