I don't normally care whether the seller posts feedback or not. I submit positive feedback just as a matter of courtesy.... and I have never had the occassion to post a negative feedback.

Too often many ebay posts all read the same anyhow ... and have no real value. Standard multiple Feedback posts that read... "AAA Seller" or "A real credit to Ebay" in response to every item sold or received says nothing as far as I'm concerned. It's like receiving a form thank you letter.
