Rules are rules, and if you get outbid within the rules, no reason to complain, let alone feel bitter. But I can think of one rule change that might increase the excitement along the lines of a "live" auction, increase the funds raised, and give those who feel sniped a chance to do something constructive about it. Since the bids are time-stamped, after the "closing" time, allow a set number of minutes for counter-bids. Then, let successive counter bids continue until an offer stands without being topped for that number of minutes.
