General question about Ebay bidding

[Runscott]

As a seller, I like to see a few bids before the last day. If I don't see any bids, then I start wondering if my item is too esoteric for ebay customers, and I sometimes pull it just before the deadline and move it to a fixed-price listing.

As a bidder, I understand the above, and so if I really want an item (even if I also intend to snipe), I place a bid if it isn't getting much action, just to encourage the seller not to end the listing.
