I gave this talk at Bolt|Peters' User Research Friday. The talk covers the challenges for studying online communities, or what I refer to as "social interaction design". Social interaction design is relevant for anyone who is developing a social product. Whether for iPhone apps, Twitter knock-offs, recipe management software, online shopping services, or even Wrigley's gum, there are social motivators that drive many user behaviors. Unfortunately, it's not so easy to "shadow" someone’s day-to-day activities in a digital space like you can in a physical space, which is why needs-finding for social interaction design requires a new set of tools and methods. I'll talk about a few remote research tools that can be used to understand the design opportunities in social spaces.
