Have to agree.
For a long time I followed the rules quite strictly. I would leave feedback the moment I received payment as that was the end of the buyers part of the transaction.
Now I rarely bother, too few people leave feedback at all. 
Ahhh - here is where we differ...
The buyers obligations are FAR from over just because they paid money!
The buyers obligations are as follows:
bove
(1) Purchase item
(2) Pay for it promptly and (optionally) advise seller of payment method and also his delivery address
(3) Be available for delivery of the package during buusiness hours OR promptly collect package from Post Office or freight company or make suitable delivery arrangements
(4) Open the package and confirm it is what he wanted and ensure there is no damage
(5) Contact seller straight away it the item differs from that purchased or it has been damaged in transit
(6) Negotiate a satisfactory solution in the case of (5) above
(7) Leave suitable feedback if deemed appropriate
Then and ONLY then has the buyer completed his obligations in the transaction - simply 'paying money' is not the buyers ONLY obligation
I realise some sellers have a rather different view to that above but read it and tell me if you think it isn't reasonable or doesn't make sense.
well in a sane world that would be true
BUT on ebay/paypal all a buyer is obligated to do is PAY.
Thats it!
Stop using ebay for selling, it is a very unreasonable place to do business.
