Whether a listing gets a bid in the beginning or towards the end shouldn't matter in the least.
I disagree with that. If you're into day 5 of a 7-day auction and you have zero bids, and let's say someone you are friend's with on the forum makes you an offer for it, most people would be more likely to shut the auction down thinking there's no interest in the item anyway, so no one will be affected by it.
It's certainly no guarantee, but I think you improve your odds by placing soe kind of bid early on, because there are others out there like me who won't close an auction if there are bids (unless of course my dog chews up the item).
