The details of any particular sale, if there is one, will only be important to the buyer and seller. No one else needs to be upset how any sale took place that made both the buyer and seller happy. Or even if a seller has the time and patience to wait for the best deal knowing what that could be... that should be ok too. It shouldn't be "it's my way or the highway" mentality. How about "to each his own" "different strokes for different folks"... personal preference is personal to the individual and individuality is a good thing. No harm no foul right?
I disagree with the above statements made by you. We refer to ourselves as a community, not individuals. We care about what goes on, on this site as it effects all of us. If you want a private sale between two strangers and want to keep all the details a secret between the buyer and seller...Well, that's what craigslist and ect. are for!
Better to foster a sense of community rather then each man for himself mentality. In order to maintain this sense of community a certain amount of trust, transparency and oversight by all is needed. This instills a sense of loyalty and responsibility, to each other, much like a close knit community or family.
In a loose sense of the word, we are a family, albeit dysfunctional at times. We fight, bicker and even call each other names...but in the end, we stand united and are quick to defend each other and the best interests of the entire community.
Better to think in terms of "we" rather then "I". Most of us, are as much concerned about the hobby as we are about our personal collections.
