Jesse,
I get it........Thing is, that the fly fishing community is a broad group. There are casual fly fishers, new fly fishers, long-time fly fishers, fly fishers who only fish with purchased flies and those flies they are told will work. There are fly fishers who only fish with the flies they tie. There are those who read voraciously all the books on flies, fly fishing, insects, etc. etc.
I guess I happen to be in that last category........those of us who are pretty much obsessed with all things fly tying/fishing.........and always curious about insects, imitations, trout biology, stream ecology, reading water, etc., etc., etc. As an often quoted phrase: "Enquiring minds want to know"......
