Figure 2: Four sketches showing platform interoperability among social media platforms. The<br />
sketches display the interconnections between social media platforms created by the<br />
possibility to cross-post content from one platform to another. Analysis by Anne<br />
Helmond, Sabine Niederer, Auke Touwslager, Laura van der Vlies and Esther<br />
Weltevrede. Visualizations by Anne Helmond, created with Adobe Illustrator. © Digital<br />

Figure 3: Walled garden data flows. The graphic characterizes the types of data flows between<br />
three social media platforms: Twitter, Flickr and Facebook. It displays the availability of<br />
four types of data exchange mechanisms that enable data to flow in and out of the<br />
platform: APIs, embed codes, widgets and RSS. The data flows are visualized <strong>as</strong> inbound<br />
and outbound data flows to indicate their direction. The availability of data exchange<br />
mechanisms and the direction of data flows have been used to determine the permeability<br />
of the platforms. Analysis by Anne Helmond, Sabine Niederer, Auke Touwslager, Laura<br />
van der Vlies and Esther Weltevrede. Visualization by Auke Touwslager, created with<br />

Figure 4: Data flow diagram depicting the various data exchange mechanisms between social<br />
media platforms. The diagram represents the data flows between the social media<br />
platforms used by a single user, myself, in the Spring of 2009. The graphic shows the<br />
interoperability mechanisms—the data exchange mechanisms of APIs, embed codes and<br />
RSS feeds—connecting the various platforms into a social media platform ecology.<br />
