4:1
Ratio of “Understanding Users” papersto “Systems, Tools, Architectures and Infrastructure” papers submitted to the Interaction Beyond the Individual track at CHI 2011.
Trouble: Exponential GrowthYour 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
Suggestion: Exponential GrowthSeparate evaluation of spread from steady-state.
Which claim is the paper making?
Trouble: Snowball SamplingThe 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
Suggestion: Snowball SamplingSnowballing is inevitable in social systems. It is fundamental to how they operate.

Show us elegant complexity.(simple ideas that enable complex scenarios)
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.

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).

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.
