Yeah. Everybody wants "more of the right kind of people", but there are as many interpretations of "the right kind of people" as there are people.

People and interactions between them are just messy. And that's not a thing there can be any tech solutions to.

For me, there are several clear step changes in groups based on size and there closeness of the relationships. A close circle of perhaps up to a dozen or two trustworthy friends is different to that same sized group of less trusted people. As the group size grows, it becomes less possible for the sort if "trusted" status of all group members to exist, and that fundamentally changes things. There's another step change when the group gets big enough that you can't personally know all the members. And another big step change when the group gets big enough that you can't even recognise all the members names (in my head, this is associated with a lot if the postulating about Dunbar's Number, however bad that research really was).
