I wonder if indexing and ranking could be decentralized. Lets say we design some data formats and protocols to exchange indexing and ranking information. Then maybe instead of getting a single Google, we could have a hierarchical system of indexers and rankers and some sort of consensus and trust algorithm to aggregate the information between them. Maybe offload indexing to the content providers altogether, i.e. if you want your website found, you need to maintain your own index. Maybe do a market on aggregator trust, if you don't like a particular result, the corresponding aggregator loses a bit of trust and its rankings become a bit less prominent.
