I see people using fingerprints directly mostly. Some download them
from key servers.

By Web of Trust I mean actually following a chain to check a key.

No, I think there are quite a few things that we can do today that
change the WoT game. People carry smart phones with near field
communication, barcode, cameras. So signing can be made a lot simpler.

Another very important and useful development is Certificate
transparency which has the effect of making the work factor for
spoofing a key a suddenly go to practically infinity.

Another resource to bring to bear is social networking

And yet another is CA issued. If you want to know that someone is
sending a message from the US gvot or a company that is organized in
hierarchical fashion, a hierarchical PKI makes sense.

I describe a hybrid approach in some detail with a mechanism for
comparing trust models in terms of a 'social work factor' here:
