  Web 3.0 focuses on the decentralization of the internet and creating a system
of interconnected and independent computers for improved privacy and security.
We extend the idea of the decentralization of the web to the social media
space: whereby we ask: in the context of the social media space, what does
"decentralization" mean? Does decentralization of social media affect user
interactions? We put forth the notion that decentralization in the social media
does not solely take place on the physical network level, but can be
compartmentalized across the entire social media stack. This paper puts forth
SMI-5: the five dimensions of social media interaction for describing the
(de)centralization of social platforms. We then illustrate a case study that
the user interactions differ based on the slices of the SMI layer analyzed,
highlighting the importance of understanding the (de)centralization of social
media platforms from an a more encompassing perspective rather than only the
physical network.
