@dansup Yes. After Bandcamp.
I had an online discussion about a Federated-Yelp that raised some interesting points that might apply to SO as well -- How do you “federate” the features that DON’T fit into the standard social media formulae? Things like “accepted answers” might only work on a centralized server.
Also, this might fall under the threaded discussion WG. I’d love to talk in more detail if you’re ever interested.
