Some of them maybe. But remember, "Choose Your Own Adventure" counts as ergodic, and those are actually improved by e-readers as it is more immersive to press on a link to make a decision than to turn to a specific page. Also, although I've not seen an electronic copy, I'd imagine "Dictionary of the Khazars", which is basically a fictional encyclopedia, could be improved by links the way Wikipedia is more pleasant to use than printed encyclopedias.
