A significant amount of the postings here have to do with questioning value or the fun that results from mis-priced bikes ("catch of the day" / "numbskull"). A searchable database would be much nicer than a forever growing sticky thread, but that apparently has been good enough for other topics ("iso / trade", "classic rides"). Besides an appraisal thread, a collection of descriptions, selling prices, and dates sold would be very helpful. I'm thinking of routinely scraping some data from eBay, but that probably is against their user agreement.
