I think we should not shy away from the subjective nature of it. Nobody is expected to get along with everyone. That is how it should be on here.

In a shameless shilling of my own ideas, I posted my take and proposed solution on rep a couple of days ago. It's on my blog if you'd like to voice your opinion.

In the end,I think it will take a number of different systems which conclude on rep in different ways. Having several points of views will allow dapps and users a better picture of who/what various accounts are.
