Into the Fediverse

The talk opens with a history of computing and networking, moving from mainframes and personal computers through online services, the early web, open source, blogs and RSS. It then shows how social platforms folded the earlier blogosphere into a few large networks. Those networks closed their APIs, relied on advertising and engagement-driven algorithms, and offered data portability that amounted to a one-way download.

The core of the talk explains the Fediverse as a federated system in which independent platforms connect across their boundaries. The speaker, a co-author of the ActivityPub standards, walks through the three parts the W3C settled on: the Activity Streams data format, a client-to-server API, and a server-to-server protocol. He describes uptake by open source software projects and by some commercial companies, along with the difficulties of network effects, portability and encryption for direct messages.

The closing section covers lessons learned. Standards bodies matter, competition between platforms gives smaller networks room to grow, and developers are often easier to reach than whole user bases. Owning a domain was presented as a source of individual control. The question period covered Meta joining the network, alternative protocols such as AT Protocol and Nostr, and efforts to add end-to-end encryption. A practitioner should take away that the open social web depends on implementers and standards work as much as on the platforms themselves.
