Farcaster is a single-tribe network, not a social network.

Big difference.

I do wonder how quickly networks need to become multi-tribe to stay relevant for the long term

IMO "design" is made up of many tribes actually — but interesting point on the pendulum swinging away from aggregation

One thesis is that we are entering the age of "network defect" — where the disalignment you get from squabbling tribes outweighs the advantage of having them all on one platform.

If so, we may need to make single-tribe networks more *useful* for doing things. 

Example: a designer guild network integrated with Figma

Multi-tribes vs Cross-tribe is an interesting dilemma: 

In my mind: 

Multi-tribe: many different pockets of society with their own closed groups on a larger network. 

Cross-tribe: unique pockets of society assimilating on an open forum. 

Multi-tribe is easy, cross-tribe is tricky. Cross-tribe needed for longevity.
