Just knowing who remixed whom with a trail back to the original.
I was thinking could we visualize the branch history in a way that allows simultaneous network analysis?
So I add a third button to remix and publish. History. Up pops up a dynamic like branch. You could then click on any two versions and compare. Decide if you want to switch versions.
This would give all the ability of forking, branching, and committing without new metaphors.
Plus might be cool way to watch resources spread across a network.
