This is pretty interesting--from Michael Habib's masters thesis, "Toward Academic Library 2.0: Development and Application of a Library 2.0 Methodology". What I like considering here is the way in which the boundaries between different modes of networking or communcation are permeable (to some extent) and overlap. All this is part of my recent interest in whether more student-oriented networks like Facebook can help facilitate contact between students, faculty, and alums. I know that the recent expansion of Facebook to the off-campus world has made some students upset, but also shows the levels of networks that can and do exist. The question remains to what extent these networks should interconnect.
