I have not used them, I will have to have a look, thanks for the heads-up. Here's a table that explains the Empathy breakdown of a Barter exchange. https://image.nostr.build/8269ab8951456dfafc2cb60d6a583c0ab612711f791e80473bd4ee4613757426.jpgb I've just posted another note, 07 Title: Barter: Empathy and the Magic Wrapping that Money Cannot Buy. It's got a pretty good analogy in there, if I say so myself 😃 and you may find it interesting.

Didn't attach, weird.
