Social Interaction Design requirements specs, cases studies, feasibility studies:

The role of social interaction designer is increasingly critical to social media startups and companies, as many of them recognize that their success depends on user experiences and aggregate social practices that are beyond their direct control. As social networking sites and social media applications scale, populations and audiences change their habits and uses. Seemingly small design and feature decisions can have significant consequences for overall use practices. Architectural features come to life as they are populated, and as user populations learn and grow with a site or service.

I have developed my own models for user behaviors around personality types common to online networking, friending, communication, and interaction. Corresponding to each personality type are different psychological interests and communication/interaction styles. How these kinds of users interact with one another, and the kinds of sites/services they prefer (and why), shape the growth of any social media product or service.

In developing social interaction design as a consultancy to social media companies, I have constructed a variety of common cultural themes, interaction models, and styles of communication and interaction. I use these, and update them, while working with clients. They serve as dynamic and living templates of how users tend to engage and participate in online social networking sites.


I have studies done for clients, and out of personal interest, in several areas of interest to social media. In some of these areas I have social interaction models and frameworks. They include:

  • twitter and microblogging conversation and activity analysis
  • social distortions in online social systems
