Shared as in 'A, agree about, take for granted as true' -- or shared as in 'B, know about, know what the person is talking about'?

Imo we have or are on the way to having a high degree of B with not so much A required. P2P -- people on all sides communicating directly with each other, rather than through gatekeepers. We can have informed disagreements and distinctions -- hopefully growing into worthwhile new (and continually updated) agreements.
