I agree with you, and I want to calculate engagement between you and me, for example, and use it to build a web of trust. Mutual engagement rather than global engagement.

So between you and me, say we talk often in replies and zap every now and then. We build up a balance of engagement and deepen our trust. These weights are to calculate that. But like you said, you might value these different than I do, which adds a wrinkle to any effort to calculate it.
