Hey Kent... We're old, not DEAD!!
IMO, the tipping factor in that equation has to do with image. People will act in their self interest when there are no observers (that they care about) to contend with, such as on the highway. But, when there's an image benefit among peers then we see the more magnanimous gestures. Its cut-throat on ebay, but in the classifieds of various forums where there's even commentary about a seller's history, there's a tendency towards much more responsible behavior. You see other versions of this when someone feels their credibility is challenged here. Big debates about stuff other people hardly care about. Its our precious self image.
So... after all this discussion it is still available. Has the time limit on polite refrainment from buying expired yet?
I don't want it.
