Just come across this. Haven’t dug too deep but sounds like an interesting opportunity. I think it can only succeed if it is fully compliant with current systems. Seems to only be mobile clients. No desktop? Are big tech going to permit this to grow? It would shut down a data mining opportunity …
Actually, they did. Back in the day all the big companies were using XMPP. For a short time it was glorious. And then little by little they started closing it off and/or making it incompatible until they stopped using it altogether.
