Greg is making many important points here. One that I wish to comment on is the idea that something that works in one situation is good in all situations. That may not be true. Greg uses the example of fertilizing ponds. This doesn't mean that we don't have much to learn from each other though. In fact, it is because of these different situations that we can learn things that people in our own areas would never have thought of. In terms of genetics, it is too easy for us to get "inbred" in our own thinking and we need these fresh ideas.
