I see this approach as a part of a larger community/family site. In this day of lockdown (covid-19) and the need of many to connect with others,
I picture a multi-layered presentation that allows a "family" (which could be members by choice not necessarily by blood). This might be measured by a Dunbar group size of 2 to 15. At this level there could be the communications of a more personal nature (lots of caveats here and extreme privacy would be essential.
Another layer of community with the Dunbar relationship number between 5 and 150, where intimacy, privacy, and self restraint would require the communications and passage of information at a more restricted level.
I guess the final level could be labeled the FaceBook level where you choose how to share your privacy data with the wide world.
I don't know, right now, how to create what I'm trying to describe, but because the electronic world that can alternately be described as much too intimate and also open to bullying and to extreme personal and anonymous attacks there is some lack of boundaries being set that members can depend on.
At the different layers different security techniques would be called on, such as:
1. Proof that the sender is properly identified,
And/or
2. Proof that the receiver or receiver group is properly identified,
3. Proof that the message was received identically to what was sent,
Even
4. Restraints that allow for anonymous messages clearly marked as such.
Of course these are all achievable with cryptography. An interesting application of some of these needs shows up in app Keybase.
The article, 'Let’s gather around the “digital hearth”' adds another layer to this scenario that I see as a possibly web-driven application. Many Web apps take on a part of this but none allows for a more complete family, community, wide world structure.
