Well, if I had it fully worked out I'd be telling people to try using my system. But vaguely...
In circles the agreement is that trust creates a 1:1 value ratio. I value the tokens you mint periodically as equal to my own, and this influences the number of tokens I give you in exchange for a loaf of bread or something. If I value the bread at 6 of my own tokens, that's the price I change you: 6.
But maybe we value each other's contributions to society differently, perhaps we consult the graph and end up with a 2:3 ratio where I trust you more than you trust me. This ratio influences prices. That loaf which I value at 6 of my tokens (times two, divided by three) I offer to you at a price of 4.
Or maybe you're working to cause me trouble, damming the river I drink from or somesuch, so the trust graph gives us a 5:1 trust ratio. In this case I'm going to need 30 of your tokens in exchange for this bread because I'm aware that by feeding you, I'm giving you energy that you'll spend harming me.
After exchange, the tokens get wrapped in a layer that indicates me as well. Since the next person to accept it will be benefiting both you and me by doing so (contributing to a system that supports our various activities), they'll have to consider the trust ratio between themselves and both of us in order to determine whether to value it. This creates a risk on my part: maybe I'll accept your token and be unable to find anybody who will subsequently accept it from me because everybody I associate finds your activities problematic. (These dynamics are all implementation details, humans just scan a QR code and see a price that was determined by the weighted trust graph).
You don't encounter tokens with problematically large stacks of wrappers because demurrage counteracts inflation. We're constantly minting new tokens for ourselves, and the value of existing tokens are constantly degrading so nobody has a token that's 100 years old. That is to say, they have a half life, they decay out of existence eventually, so there's an incentive to continue to be trustworthy and useful, rather than just hoarding enough that you can then opt out of being trustworthy for the rest of your life.

The ratio we end up will not be a function of how many people trust you, or how many people trust me, it'll only consider cases where I've trusted somebody who trusts you, or where you've trusted somebody that trusts me. We opt-in to the asymmetry by using variable degrees of trust to enable or prevent the activities of our peers. It restores balance to the "vote with your wallet" situation. Currently, the only way to vote with your wallet is to vote yes or to abstain. This lets you vote no.
For a first pass I'm considering using https://github.com/cblgh/appleseed-metric for the trust graph. But I don't intend to start by making apps like the one I've described here--nothing so politically charged as money. I figure I'll get the protocol working with things that are low stakes and easy to get on board with and try my hand at making something money shaped only once it's performing well for other stuff.
