Phillip, you deleted your post!

You're right, the Yahoo thing is more of a true auction. In a true auction, all people present are allowed to counter bid. If someone bids with 2 seconds left, they are not allowing someone else to reconsider. Sniping is sniping, motive doesn't matter. If something is truely your "highest bid" and what you're willing to pay for, then why don't you bid that much at the start of the auction?
