@helge may be I don't understand all the details. However, I can imagine a social interaction based purely on DID and content-addressable data. Including social graph, protocol agnostic communication, seamless data synchronization, and no provider/vendor lock-in. One of the examples is Nostr. At the same time, I think, modern location-based systems are a huge risk of vendor lock-in. I'm really tired of changing my identity, every time when I disagree with the provider. We should stop this madness. DID is the future.
