I agree 100% with the idea that we need to build the next generation web-of-trust so that from the user's perspective it looks like a social networking app/game.
Trust grows organically as your interact with others. Our computational model of "trust" needs to work the same way.
Part of the problem with existing web-of-trust usability is that it makes "trust" too explicit and coarse. It would make more sense to tell the user "this message is signed by the same person you've had 70 conversations with before, and who has liked 40 of your photos" or "this message is signed by someone you've never interacted with before, but they have a long history of interacting with your friends X, Y, and Z".
