I don't mean for this to come off as a rant (so don't read it as condescending or yelling via text), but posts like that are a bit of a pet peeve for me.
I think, in general, it's best to post stuff like this after the auction ends. If it's a giant, well-publicized auction (like Phillips or Christie's), then it doesn't matter because a ton of people are going to be looking and bidding anyway. For the smaller houses, however? Not so much. If you're a prospective bidder, the last thing you want to do is add more eyeballs to the smaller auction before the gavel goes down. And if you don't plan on bidding, a post-mortem is probably the best and most respectful route. Same goes for eBay auctions, IMO.
Others can feel free to agree or disagree, but that's just my two cents. And yes, this one struck a nerve because I have been eyeing this lot for a couple weeks now...
