I forgot where I read about it, but there are some limits to certain human social groups we all share (paraphrasing from what I remember):

---------------------------------------------

Best friends: 2-3

Close Friends: 15-30

Friends / "Friends": 100-200

Acquaintances: 1000-2000

---------------------------------------------

Something along these lines. With the biggest kind of aha moment for me being that the army (notorious for optimizing everything to the highest degree) has organized itself in similarly sized groups:

---------------------------------------------

Squad

Section

Company

Brigade
