Abstract

Decentralized online social networks (DOSNs) represent a new way of organizing online communities and present both challenges and opportunities. The decentralized design of spaces like the Fediverse provide more indepdence, but this increased autonomy comes at the expense of collective action problems which must be solved in new ways. This work considers how the collective actions problems are addressed in practice and designs potential new ways to solve them.

1 Introduction

The World Wide Web has reshaped our communication landscape with pervasive economic and cultural effects (; ; ; ). The Internet, which forms the technological underpinning for the Web, solved the problem of connecting disparate networks, computers, and operators around the world by creating a flexible system based around interoperability: protocols like TCP/IP and HTTP allowed enough standardization for meaningful communication while allowing individual systems to still experiment and retain control over their data, access, and code. One key to its success is that the largely decentralized nature of the TCP/IP protocol allowed new nodes to join the network with limited friction ().

This approach has facilitated a strong network of person-to-person communication, developing various systems to facilitate communication between their stakeholders. Early Internet developers used email to coordinate their efforts (). Later, early online communities developed on Bulletin Board Systems, USENET, and discussion forums (; ). The blogosphere of the 2000s became a significant media power in its own right and many alumni from this era successfully transitioned into roles in traditional mass media, which itself adopted many of the norms and practices from the bloggers (). Further, the rise of social networking sites brought online communication to a larger audience (see ) and marked a shift in the organization of communities from being around topics to being around people ().

The history of the design and use of these systems each reflect the needs and values of the people who built and use them. Early email, for instance, was closed off to academics and government employees who quite literally met in person to plan the early email programs (). As operators could easily be mapped to their real name and identities, there was less need for security and privacy protections when the protocols were first developed.

Note that in 2021 and before, PRC administered the survey over the phone, while after 2021 they administered the survey online and via mail.

Online communities have not come without problems; connecting so much together creates a number of benefits, but it also comes with challenges. Significant resources are spent by the companies who run them to try to keep them free from spam, harassment, and illegal content (). Differences in international law and norms can make this a challenge and norms can vary by culture and location (). The largest platforms have becoming increasingly closed off and less transparent to researchers (). Concerns persist over the dominant economic model for the commercialized Web, which relies heavily on advertising and attention ().

While the commercial Web has received significant media and lawmaker focus, it does not represent the totality of Web. Much of the early online communities were run by hobbyists and non-profit organizations (). Projects like IndieWeb have sought to create a more decentralized Web, where people own their own data and can interact with others on their own terms (). Today’s Fediverse is an extension of the original spirit of the Web: powered by the ActivityPub standard, the Fediverse is a collection of interoperable and interconnected websites that retain their independence and autonomy. With millions of active accounts, the Fediverse has established itself as a viable alternative to the commercial Web.

While significant work has gone into technical interoperability on the Fediverse (e.g. how do we pass messages between servers?), work on social interoperability is still emerging (e.g. how do we determine which servers we want to get messages from?). Fediverse servers must handle many of the challenges faced by the commercial Web in addition to some of the new challenges imposed by their decentralized design. This prospectus outlines a research agenda to understand how the Fediverse handles these challenges.
