Trust is definitely the glue that holds our society and economy together. In my experience, fortunately most of the people I interact with are "trustworthy", not all, but most seem to be.
With regard for buying and selling on this site, whenever someone reaches out to me about purchasing an item I have for sale, I will only deal with them if they make an offer thru the site, not with the email exchange, that way if they jerk me around, I can report them to Audiogon. I had a guy go back and forth with me on the purchase of an SACD player, we came to terms on the price and when he arrived at my door he said on the drive he decided to offer me $600 less than we agreed to. To bad he wasted his time on that 90 minute drive to and 90 minute drive from my house. I don't deal with people like that.
