In my opinion, both the buyer and seller should stay on top of things until the transaction has been completed satisfactorily. Whether I'm buying or selling, I like to do everything possible to make sure the transaction goes smoothly for both of us.
Regardless of whether I'm buying or selling, I answer all emails in a timely manner providing any and all relevant information and I make sure the other party knows that I'm available to them should they have questions. I think it is the courteous and responsible thing to do. After all, we are exchanging money and equipment with each other with nothing to base our trust on but the feedback system. I think it is important as well as reassuring to make yourself available throughout the transaction.
Personally, I enjoy the "interaction" with the other person and it's been my experience that they enjoy it and appreciate it as well.
