I think when it comes to the average pond keeper, folks want to enjoy a pond like they do their modern auto. Get in turn the key and drive it. How it works is less of a concern until it doesn't.
Staying with the auto analogy, those who work on antique autos know their workings very well and enjoy the puttering and keeping them fit. These folks whether they putter with filters or autos have a better understanding then the turn key folks. I think we call them DIY'ers.......
I liked using the auto analogy because of our subject's use of cubic inches in engines and relating it to horsepower and filter design. I won't "bore" you with any more auto talk except to say in both threaters a smaller more efficient "foot print" has been the trend for a while now.
Jim's passion for helping us all understand how and why a filter works has helped move the few turn key folks a little closer to understanding. Now the big problem is getting enough folks to read his material. Remember back in school when they were reading requirerments
