This is a great blog post by nostr:npub1jlrs53pkdfjnts29kveljul2sm0actt6n8dxrrzqcersttvcuv3qdjynqn about some of the things we hope to see in a decentralized web of trust (better curation of information) as well as some of the traps we hope to avoid (degradation of privacy from metadata).
All in all I think decentralized WoT will be great for privacy if for no other reason than that it will allow us to opt out of the existing panopticon of legacy centralized big tech platforms. Even normies will eventually opt out, once WoT provides capabilities they don’t currently enjoy. But it’s always good to do our best to anticipate and understand these types of problems before they happen, lest they catch too many people by surprise.
