too bad Audiogon seems to have morphed to fussy, picky buyers

Oh I don't know. I've only had a limited number of transactions on Audiogon and only encountered one rude idiot. That's not bad at all compared to what I've found on eBay. Craigslist, despite what you hear, has always been easy and cordial. That's likely because Craigslist items are low dollar compared to Audiogon. Yes, sales have slowed notably here. What used to be snapped up in half an hour may well now not sell at all. Oh well. If you're a dealer that's serious. If you're just having fun, ces't la vie.

Fussy, fussy, fussy!
 I’m never going to be able to sell another item after the one and only item I ever sold was greeted with damning feedback by the buyer.
I casually glanced at the faceplate of the amplifier I was selling (and had just bought, myself), and found no visual blemishes.  I advertised it as such.
Well, the dogs of hell descended on me from the buyer who found multiple blemishes and was highly irate.  
Who the hell looks at an amplifier with a magnifying glass? When it’s in a system.  It’s pretty well blended in with the rest of the components.  You don’t buy a stupid looking box for its beauty.   You buy it for how it sounds!
He claimed he won’t be able to sell it in that condition.  Well, I bought it.  I had no problems with it.  I only sold it because it was not compatible with my system.

Fussy. Picky. Hand-holding. Blame it on the Millennials!

tomcarr you said it. They have more money than brains and expect everything handed to them on a silver platter. Then the hand holding begins. It's because mommy and daddy took care of everything for them. Spoiled brats IMO. They should have been disciplined more when they were children.

Only local cash and carry sales for me as of 18 months ago! Totally disgusted with PayPal scammers and low ballers wasting our time with offers less than 25% retail, even for current iteration gear. Agree that I’d rather keep or gift my used gear rather than reward these jerks or have my payment again reversed by PayPal. Also agree that it’s not only Audiogon. That said, I’ve had more quality buyers on US AudioMart although responses are much slower, sales often taking 6 months or more.

Sellers blaming Audiogon for the customer and market? 

If if you don’t have a good product at a fair price then guess what....

Just the other day I encountered a dealer wanted only 30% off of list price for 10 year old amplifier. As a negitiation tactic I was offered 2.5% discount if I paid cash. I kindly explained that I can find a new (less than 1 year) one for only 5% more and the new one would not be dinged up with deep scratches where the paint on the chassis was rubbed off. The same amp is still listed two months later....price dropped 2%...it will probably list for 9 to 18 months before sale with incremental discounts of 2% each month. 

Classic example of seller knows better than the market or buyer.....
