<p class=MsoNormal>First ACM SIGCOMM Workshop on Online Social Networks
(WOSN) <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><a href="http://www.sigcomm.org/sigcomm2008/workshops/wosn/">http://www.sigcomm.org/sigcomm2008/workshops/wosn/</a>
<o:p></o:p></p>

<p class=MsoNormal>Call for papers <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>With half a billion active users, online social networks (OSN)
have attained critical mass and triggered intense research interest in
collaborative systems and the analysis of the structure and properties of
online communities. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>WOSN will bring together researchers and practitioners to
discuss the challenges and important questions posed by emerging online social
applications. Of particular interest are problems related to network and system
architecture design that can best support emerging and future social and
collaborative systems, and how those social networks can shape the design of
existing distributed systems and real networks. The goal of the workshop is to
facilitate cross-disciplinary discussion of relevance to computer networking,
involving novel ideas and applications, and experimental results. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The workshop solicits original, previously unpublished ideas
on completed work, position papers, and/or work-in-progress papers. We
encourage papers that propose new research directions or could generate lively
debate at the workshop. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Topics of interest include, but are not limited to the
