The only thing this new feedback format will create is the constant and ever increasing need for sellers to sell their items even cheaper than the next guy.
I keep working around ebays changes, knowing they are on a steady self destruct course. I use a few auctions to point to my store sales. I use ebay store to farm my website sales, which by far outpace my ebay sales. I also buy antiques and collectibles on ebay and sell them in a minimall for 300 percent markup. Just a case in point how ebay is becoming cheap bay at our expense.
But I would still point out, that it does not pay to get negative about them. You just have to work around what they are doing to keep making some kind of profit from your business plan, using their expensive services.
