I find most sellers to be average, or as you put it "satisfactory"... I expect a seller to do their job and not pander to buyers in an attempt to score points.
The seller sells, the buyer buys, there's nothing special in that, or do you spent 10 minutes at Tim Hortons while the clerk tells you what a wonderful job he/she is doing and please reward me because I did my job...
If a seller goes above the call of duty or disappoints, the feedbck is adjusted accordingly, but 90 % of my sales and purchses have zero personal interaction between the seller and buyer, which is the way it should be.
If you want to be loved, call your mother, it's not a buyer's job to stroke your ego, they are here to buy something, not make new friends....
If you don't like the concept of starting from the middle of the road aka 3 stars that's fine, but it does not impose a penalty on the seller so leave the violin in the case, it's unprofessional and unbecoming. You are absolutely right, buyers don't give a rats ass about your personal life, they are are here to buy something, not provide an outlet to a sellers personal drama.
Why are so many eBay sellers unable to grasp the concept that business is business, and the concept of community and shared experience is nothing more than eBays way of controlling you, or do you all spend your mornings at McDonalds wolfing down a Big Breakfast and listening to the trials and tribulations of the staff...
If you haven't gotten the point yet, ask yourself this, when was the last time you gave a clerk at Walmart a 5 dollar tip ?
But seeing as you brought up the subject of housewives/mothers, I much prefer to buy from them because they are hungry for the exact reasons you intimated and they are typically extremely ingenius because necessity is the mother of invention. The self proclaimed expert eBay sellers could learn a lot from them because a mother/wife trying to earn a few bucks to take the kids to Disney World has the best grasp on reality.
