2. Ratio of “Understanding Users” papers to “Systems, Tools, Architectures and Infrastructure” papers submitted to the Interaction Beyond the Individual track at CHI 2011. 4:1

3. Trouble: Exponential Growth Your usage data is not really compelling because only a small fraction of Facebook is using the application. Worse, your numbers aren’t growing in anything like an exponential fashion. – CHI metareviewer, paraphrased

4. Suggestion: Exponential Growth Separate evaluation of spread from steady-state. Which claim is the paper making?

5. Trouble: Snowball Sampling The authors’ choice of study method – snowball sampling their system by advertising within their own social network – potentially leads to serious problems with validity. – CHI metareviewer, paraphrased

6. Suggestion: Snowball Sampling Snowballing is inevitablein social systems. It is fundamental to how they operate.

11. sociotechnical studiersbuilders Fatal Flaw Fallacy [Olsen] Ecological validity at the cost of internal validity [Ackerman 2000], [Barkhuus and Rode 2007], [Chi 2009], [Greenberg and Buxton 2008], [Kaye and Sengers 2007], [Landay 2009], [Lieberman 2003], [Olsen 2007], [Zhai 2003]

12. sociotechnical studiersbuilders Show us elegant complexity.(simple ideas that enable complex scenarios) We let people type messages up to 140 characters. That’s it? What is possible now that wasn’t before? Nothing — but focus on emergent social activity. Can you add multitouch? Not using IE8.

13. socio technical studiers builders Build a technically interesting system (that is hard to spread or evaluate), or Simplify to a system with socially interesting outcomes (that builders find less novel).

14. The contribution needs to take one strong stance or another. Either it describes a novel system or a novel social interaction. If it’s a system, then I question the novelty. If it’s a social interaction, it needs more development. – CHI metareviewer, paraphrased Build a technically interesting system (that is hard to spread or evaluate), or Simplify to a system with socially interesting outcomes (that builders find less novel).

15. Create a shared understanding of research contributions

16. social technical New forms of social interaction Shared organizational memory [Ackerman 1994] Designs that impact social interactions Increasing online contribution [Beenen et al. 2004] Enable fluent social interaction in a new domain Socially translucent systems [Erickson and Kellogg 2000]

19. In conclusion introduction: What are our millennium challenges? What is our relationship with industry and walled gardens? How can (and should) we evolve our standards of proof?
