How I see it, agreeing completely with Byte Commander's comment: I try to constantly check through all my posts (maybe one or two a day) and see if I can improve them.
If I see any other post anywhere I can improve, however old, I try (respectfully) to improve it, unless I think it should be deleted. The site as it is, as a whole and in all its parts, should be as good as possible, and I should make it as good as I can, and that's all.
