Average College Kid's Social Sphere Across Digital Channels

Online Media Daily reports on a study on U. S. college students' use of social networking and communication. "Without factoring in contact overlap, that means every student in the nation has a potential reach of 671 consumers, according to a new "University of Media" study conducted by Mindshare's Business Planning group in partnership with Alloy Media + Marketing and Brainjuicer" Does this mean that if we could teach one college student about use of library resources we could potentially be reading 671 consumers of information? We can dream, can't we? And for all of you "mobile librarians" out there, the study reports that text messaging is the most common method of communication among college students. My friend Drew Smith reminds me that the average number of cell phone contacts reported is about the same as reported for the number of friends that humans tend to have - around 150. See http://en.wikipedia.org/wiki/Dunbar%27s_number for a theory about that. (Thanks to YPulse for the info about this article.)
