My theory assumes as a presupposition that people are only likely to travel a certain distance to see others, since time is a scarce and non-renewable resource.

If interests are fragmented, the number of people we both share interests with and are friends with within a given radius becomes smaller. Facebook might help a bit for organizing events and maintaining existing ties but it also contributes to the dopamine rush above. Some sort of ways to connect new people with one another within a local area could be helpful. I found Meetup interesting and useful but could be improved upon. I used to attend some events organized by WeWork and those felt more energized but still no real friendships emerged. The only thing that really helped make new long-term friends for me was sharing a co-working space with people who had some interests in common.
