I think you're considering two different things.  The first is social
network analysis as an analytic methodology.  The second is the
application of that methodology to technologically-mediated social

So, I think the answer to your question from the first perspective is
'no', the methodology available to you does not inherently change when
studying mediated networks vs. non-mediated networks.  Stanley
Milgram's classic small world experiment was a network study of
relationships mediated by the communications technology of postal mail.
  This does not preclude the development of new techniques.  The benefit
of analyzing mediated networks, of course, is that it enables the study
of very large networks, which may lead to new techniques.  However,
this is a consequence of the size of the network of interest, not its

The answer to your question from the second perspective is, I think,
'probably not'.   Mediated networks have been studied, but I'm not
aware of any research that compares the two to attempt to discover any
differences.  I'm currently studying the evolution of a community of
fan fiction authors and readers through their blogging activity at, but that's not the same thing...

This isn't true at all.  This has been a active area of research over
the past few years. See, for example:
