Dave; I don't concern myself with feedback. If I get it, that's fine, if not ... ain't no big deal! Most positive feedback (with few exceptions) is a meaningless canned standard response that is used over and over again by both buyers and sellers.

I do make a serious attempt at posting feedback for others ... but it's entirely optional for others what they wish to do. Like you; on occassion, feedback I post for others may not be until weeks after the fact... when I get around to it.
