I don't know if this is worth it's own thread so I'll put it here to get reactions, it's just an idea I had that might work well with bitcoin. I'm not suggesting you do this biddingpoind, I think the "normal" auction site is an excellent service, and this idea is a bit of a game.
So I noticed that I kind of like bidding on thing, even things I don't really need. But, even though I like to click the bid button, I usually wait until near the end since there is little reason to go early and I think some good reasons to wait. One was mentioned, bitcoin value can rise a lot in a few days even and I'd hate to pay 70BTC for a $25 Jack in the Box card and have the BTC go to parity before it even ships to me. Another reason is my fellow bidders psychology. They may decide some piece of art is worth 120BTC to them and bid it thinking that it's as high as they want to go. If I wait and outbid them at the last second then they won't have time to change their mind, if I go early they have plenty of time to reason, "Well, someone else thinks it's worth more, maybe it is after all, hmm, okay I'll go a little higher and see if I can get it", but they are less likely to outbid themselves without the stimulus of my beating them. So this leads to sniping, which isn't bad, except maybe for the seller if they get a lower price because some people who might have gone higher didn't have time.
Okay, the idea.
Pay people to bid and/or
pay people for being the leading bidder for a length of time. The beauty of doing this with bitcoin is that you can require bidders to have the money on account with the auction site so that people cannot freeroll by collecting payments for bidding and defaulting if they win. However much the bid is, that much will be locked up until it is paid to the seller or someone else outbids.
Now instead of paying directly you could have a point scheme and pay people according to their ranking and this way you could know the total compensation you would owe per month or whatever. So pick some amount to spend on this promotion say 1000BTC and then if someone has 4% of the total points at the end of the month they get 40BTC credited to their account.
I think this will get people to do a number of things that will be great for the site. Bidders will watch the site all the time, knowing that even if something pops up that they don't really want, they can earn points for putting in a bid. Only the worst imaginable items will go bidless, sellers will appreciate this. Also people will not wait until the last minutes which I believe will lead to higher final prices. The whole thing will feel more like a game too and the uniqueness of it should lead to some extra word of mouth. People who do find things that they like may be more inclined to go higher since they are also getting a kickback for it, and may have previous bonuses to spend. People can convince themselves that the points are worth more than they really are when they are looking for a reason to bid. Then can even tell the wife, "whoops, I didn't mean to win, only trying to snag a few points, sorry"
Anyway, feedback please. Or even better, implement it so I can see if it's as good as it looks to me.
