That's true, I don't know how to solve that. I could mitigate it by removing 'downvotes' so maybe the 'reject' argument might have 100 votes (due to being flooded) versus '10' for the 'vouch' argument, but then people could make up their own mind as to which argument is valid.
I like this, I think the main idea is a system for tracking sources and being able to see cohesive narratives, maybe with an emphasis on the visual. Truth tends to converge so would def be useful.
I also like the idea of it being more of a natural process rather then a person catering every individual 'connection'.
