Venkatesh Rao thinks that the Nazi bar analogy is “an example of a bad metaphor contagion effect” and points to a 2010 post of his about warren vs plaza architectures. He believes that Twitter, for example, is a plaza, whereas Substack is a warren: A warren is a social environment where no participant can see beyond their little corner of a larger maze. Warrens emerge through people personalizing and customizing their individual environments with some degree of emergent collaboration. A plaza is an environment where you can easily get to a global/big picture view of the whole thing. Plazas are created by central planners who believe they know what’s best for everyone.
