The final speakers in this Digital Methods plenary are Axel Maireder and Katrin Jungnickel, whose interest is in the uncertainties of the Facebook timeline. Facebook has continued to tinker with how the timeline is selected and presented for several years now, and this affects the flow of communication on the platform; what, then, are the factors which determine that flow?
This study combined content analysis and user surveys, but both these approaches have their drawbacks - it is impossible from the outside to track the content of users' timelines, for example, but surveys of users also suffer from self-reporting biases. In the end, the researchers asked users to copy the links they received through their timelines into an online survey, and to discuss the content of the URLs and the Facebook friends they received them from. Issues with privacy as well as the tedious nature of this approach also affect the results, however. Some 550 users participated in the study.
