That's not quite true. It's not just that it doesn't interest me; it's that it risks to actively damage my ability to collect what interests me by paying a reasonable amount for any item. It risks also stagnating the market by causing sellers to believe that they MUST ask a certain amount of money for any item that has already achieved a certain amount through auction or sale. In short it risks to set in stone prices which are and always will have to be, flexible.

This problem has already been encountered by buyers and sellers alike as a result of the Record Collectors' Price Guide (which is now largely discredited), and whereas discogs provides a useful range of prices which adapt to circumstance, having a price on 45cat.com or 45worlds.com might give unreasonable expectations to sellers and stop buyers from otherwise making purchases.
