Mikey, I see no problem with discussing live auctions. Sure, people actively involved in the bidding may be annoyed, but in the case of this particular item that probably equates to about a 0.01% of the membership of this site, if indeed that high a percentage.
This auction wasn't a misdescribed item and had already attracted many hits and bids. In this case it would be naive of anyone to think that there was a bargain in the offing.
Unfortunately, in this day and age a great deal of the Holy Grail Records that we obsess about are going to be auctioned on Ebay at some point. Not being able to discuss these while they are ongoing will be a major downer, especially as the vast majority of people on this forum will probably never get to own some of the stupidly rare items being discussed.
Many interesting and salient points came out of the discussion about the Walter and the Admerations disc, for example, that was auctioned comparatively recently. It would be a shame if the first we got to hear of it was discussing what it sold for.
I think the benefits of being able to discuss ongoing Ebay auctions vastly outweigh the negatives and self-interest of the tiny minority.
