Real social structures have some cost to discoverability, with increasing layers of cost/friction for each additional attempt to uncover more information. This friction is beneficial—it dramatically cuts down on casual busybodies, griefers, and nosepokery.
But online spaces are built by techno-utopians who think there's no such thing as too much of a good thing and continually push their platforms to uncanny levels of compulsory discoverability. All the negative consequences be damned.
