The issue you quickly run into with that kind of system, is that duplicate topics come up quickly.
I have a similar system I am working on mainlining, that just ignores some of that heavily relies on Pueblo links for easier navigation. Navigation gets more difficult without that information - though a typed column could resolve that. But the UI design for that seems... well, not sure how I'd do that.
(Graph Storage SQL enginge for duplication between say, wiki and MUSH, using the kind of graph-mapping we use to remember things)
Mind that this is an administration view, but just like you, I'd love to see that in actual use.
