@maikel this is a very cool and relevant direction that explores new social networking use cases and areas, and where reflecting deeply on the social side of the equation will probably pay good divident when it comes to implementing the supportive technical side.
I posted the other day about the social networking direction I am most interested about, which requires healthy ecosystem and inclusive commons based collaboration.

SX considers your applied research area to be exploring the Personal social networking paradigm, which in a more general sense also facilitate the notion of what it means to be "working in commons" on things that are "commons based".
Trust and safety are major concerns, I gather. I am not sure what is the status today, but the Open Hospitality Network at one point was investigating an ActivityPub based platform similar to CouchSurfing, where these aspects were also of key importance. @mariha hosts this community.
