Call for papers for Hypertext 2013 conference announced! Abstract deadline Dec 13, 2012! ht.acm.org/ht2013 #ht2013 

Track 1: Linking people (Social Media) is likely to be of interest to many people on this list.
http://ht.acm.org/ht2013/tracks/social/ 
Social media has revolutionized how people create and consume information and interact with one another. On sites such as Twitter, Facebook, the various blogs and wikis, people share ideas, opinions, and interests, and respond to those expressed by others. Social media systems have thereby generalized the conventional notion of a hyperlink to imply connections between individuals in particular, via their shared content, media, concepts, and other artifacts. A characteristic property of this new genre of connections is that they promote rich social interactions among individuals involved in the sharing and artifact-building process. At the same time, the growing popularity of these systems presents some challenges: how to motivate new users to participate, how to sustain communities over time, how to manage social media traffic or decipher the large information spaces engendering the interactions.

Making sense of these complex interactions has attracted significant attention in various research communities over the recent years. This track is geared towards developing deeper insights into the mechanisms of information exchange, user and network characterization as well as the discovery, analysis, and modeling of the dynamic social processes in these systems. It provides a key forum for researchers and industry practitioners to exchange information regarding advancements in the current state of art. Addressing several problems in this space necessitates expertise in a variety of domains, spanning Computer and Information Science, Social Sciences, Psychology, Math and Economics. Hence submissions promoting interdisciplinary collaboration are highly encouraged.

We invite original, high-quality submissions on all aspects of social media.
