This is from an older interview on the Read/Write weblog, with the founder of WebJay Lucas Gonze, but his comments on how P2P-systems can actually re-inforce the centralization of taste are of interest:
“”’Where does WebJay fit into the ‘P2P system ecosystem’, in your opinion?”’

Lucas: Webjay decentralizes taste. This seemed to me to be the next frontier after decentralized network connectivity was fully colonized by the filesharing people, because the decentralization of network connectivity created more centralization of taste, not less.

The first reason is that you traverse filesharing networks by search — search-driven navigation relies on memorable identifiers to search for, for an identifier to become memorable requires marketing, and marketing is a tool only available to large centralized entities like major labels. The second reason is that, when demand drives supply as it does on filesharing networks, being known is a condition of becoming more known. The expense to break into this system is currently covered by marketing dollars.

To decentralize taste I needed to break that cycle. I chose to stick strictly to above ground networks because unauthorized material is cleaned out by DMCA requests and lack of bandwidth for consumer ISP accounts. The more marketing dollars are going into an artist, the more DMCA takedowns are issued and the more downloads there are to blow through upload bandwidth. If a rights holder has a problem with a URL, I don’t want the URL, so it’s convenient that such rights holders will knock down those URLs for me. Everything I do is out in the open because open networks are, for now, naturally inhospitable to centralized taste.”
