I believe that Stack Overflow belongs to a time when VCS was the exception rather than the rule, codebases were scattered across many different providers, discussions took place on dedicated channels or mailing lists, documentation was scarce and of poor quality, and tooling was limited to the most essential. All this added friction to any form of shared knowledge of being built by the general public.
