Idea: make a network of ebays, with each one specializing in a certain category: cars, collectibles, etc. That way, a community forms around each ebay, and each community can develop its own quirks that make sense/are convenient for that particular ebay, have its own experts (perhaps with karma to differentiate those experts), etc.

This is edgeio's buisness plan right there.

Not a bad idea at all, I can see your logic in this. Better for every network to do one thing well and leverage some long tail action.
