The ranking itself is perhaps
less interesting than what it
reveals. The most frequent-
ly cited source was neither
aglobal news outlet nor an ac-
ademic database, but Reddit.
This signals a fundamental
shift. Community platforms
are no longer simply channels
for content distribution. They
have become spaces where
customers share experiences,
experts exchange insights, and
other stakeholders validate—or
challenge—a brand’s claims.
These interactions, in turn, can
become source material for
AI-generated responses.
