That's true. You also need to be sensitive about echo chambers, and that's something humans also routinely fail at. I trust credible experts, not the self-selection of Twitter accounts telling me what I already believe.

Even if you 100% trust everyone you follow, and also believe them to be entirely impartial, the nature of Twitter makes it so easy to spread misinformation (mixed in with real stuff.) Twitter is optimized for viral content, not true content.
