I do not disclose email addresses anymore. Friends who want to reach me must use something else, like XMPP.
This arrangement works well enough but there is a snag. Tech-challenged folks often receive an email and they want to forward it to me. But email apps and XMPP apps are in separate bubbles.
In principle, the email app should have a “forward to xmpp” feature. But even if that were to exist (does it?), the low-tech demographic likely uses whatever web app Google pushes, which would not likely have such a feature.
So it seems a email→XMPP gateway is needed. I find this. That’s not a service. It’s kind of like: go build something. Is that where we are? Is that the state of the art?
