Interesting! In my stack of notes — I have this saved for — well, for what I don’t know. I found the concept of bonding vs. bridging interesting and wanted to include the idea in a story somewhere. I think johnronand introduced me to the concept.
Also, I have Putnam’s book Bowling Alone on my list of “I want to read.” :)
Just last night I was thinking about John Dunbar(Kevin Costner) in Dances With Wolves. A perfect example of bridge building!
