The crazy thing about ActivityPub is that there's way more projects out there than you might realize. A seasoned Fedizen might be able to easily think of about a dozen or so platforms in the space, but I wanted to take the time to focus on the more esoteric ones we've come across.

Feel free to share ones you've found!

• Ibis - ActivityPub-based Wiki
• Transit Fedilerts - a bot system that sends transit notifications.
• Corteza - DIY federated Salesforce thing with an AI app building framework.
• Dokieli - decentralized publishing with ActivityPub and RDF, may have Solid capabilities?
• FitTrackee - self-hosted fitness tracker, ActivityPub support in development.
• NeoDB - a review platform for just about everything, some incredible ideas about data integration.

More to come!
