Yes but "small focused circles" is essentially the extent of where WoT works. It doesn't scale to larger or loose communities.
It seems like everyone is trying to find a way to make a global trust network (keybase, LinkedIn, etc.), when all you need most of the time are small circles of trust (dev groups, activism organizations, etc.).
I think the decentralized nature of WoT is actually a better way of structuring things, since it makes mass surveillance much more difficult.
