Jim it's still interesting, I think it may be a case of the membership trying to figure out what components are immediately applicable to ponds. I know that's true in my case anyway. I enjoy learning the science behind my interests, but on the other hand when It's time to change the oil on my pickup I don't research to learn what species of dinosaur it came from, my immediate need is to identify what weight and type of oil, and where can I buy it?
I see our membership as diverse, and there is absolutely a faction that delves into the details. But I also think there is probably a larger segment that is looking for more pond how-to, rather than how it happens?
It's only one guy's opinion, and worth what you paid for it, but maybe integrating some of the info into a real world pond setting will help illustrate the repercussions and possibilities of what your discovering?
