Apple introduced a screen snapshot shortcut.
This made it supper easy for anyone to share what they’re doing with their iPhones.
This also allowed developpers to easily upload screen shots of the apps they develop to iTunes.
By making sharing super easy and straight forward, Apple empowered its tribe to communicate with each other (1st aspect of tribes.) This also empowered the tribe to communicate with the outside world, thus recruiting new tribe members (2nd aspect of tribes.) Apple also provides multiple platforms and opportunities for the tribe to communicate with the leaders, and the leaders with the tribe (3rd and final aspect of tribes.)
These were the 3 pillars that make a tribe from Seth Godin’s book «Tribes».
