Jeff, I am willing to bet you do not sell much on ebay, so you don't understand a seller's point of view, or why many of us have made it policy to not leave feedback until it is first left for us. I have been selling on ebay now for 5 years. It is the buyer's responsibility to start the feedback ball rolling. The feedback the buyer leaves for the seller is much more important than any that a seller leaves for a buyer.
A buyer should comment once the item is received as advertised in a timely manner. If there is a problem with the item, contact the buyer so they have a chance to make it right. A seller's feedback rating is very important for his reputation on ebay. I will not leave any feedback, positive or negative, for any buyers until they leave it for me first. This allows me to retain the option of returning a negative and then petitioning to have the feedback mutually withdrawn. This is my only recourse against buyers who want to leave a negative. If there is any kind of actual problem with an item I sold I will do everything I can as a seller to remedy the problem. In the past this has meant I issued full refunds and wrote it off as a loss. I would rather take a loss than receive negative feedback on a sale. If buyers like Jeff feel they do not want to leave feedback first, I guess we just don't leave any feedback for each other... no big deal, I have a 355 rating with 98.9& positive... I don't really need your positive point, and I don't waste my time sending emails hassling people to leave feedback. Leaving feedback is completely optional for both parties. But I simply will not take the risk of a buyer leaving me a negative where I have no recourse to do anything about it.

It really is almost impossible to have a 100% feedback rating, because some (very few, but they are out there) people are just unreasonable and want to act like total jerks. If you want to maintain a 100% positive rating, you must be extremely shrewd. I would say just proper honest business practices and putting the customer first will always pay off in whatever you do.
I try to be the best seller I can and will do anything to make sure a transaction is a good experience for the buyer. My feedback rating reflects this.
