Well, jomini, your walls of text are just intimidating, even to experienced players. Most of us try to be fairly succinct with our strategic ideas. I'll admit that most of the time when I see your huge paragraphs, I usually just scroll right by, because I know you're going to be indulging in intimate minutiae. I'm not saying there's anything wrong with that - you obviously enjoy the hell out of it - but most people, even those who would consider themselves professional/good/experienced players, are not really interested in that.
Think of it like this: I'm in the sciences. I love science just for the fact that it's science. But when I start nattering on about quantum field theory, most people just kind of zone out and stop caring. But if I tell them scientists have figured out how to make a functioning warp drive or a cure for cancer, they're all ears. Most people don't really get the concept of research for research's sake - they only care when you have something tangible that effects their lives.
In Dominion terms, people care if you come up with a game-shattering combo, or figure out if a card is really good. They don't really care about niggly little interactions, unless they're in the Puzzles subforum. They don't care about elaborate statistics or whatever else. And oftentimes, the interactions you come up with seem overly involved, when there are simpler ways to do it - like I was saying about Scout being a better enabler for Herald than Navigator, because Navigator is a terminal, and then LastFootnote raised the point that it was designed as an end-of-turn style card. That's not to say cards can't fill roles they weren't designed for (Donald X isn't omnipotent or omniscient), but that until your out-of-the-way, involved, depending-on-multiple-things-going-right interaction actually bears fruit in actual gameplay, most people just don't care. And for the most part, keeping it simple tends to work better in Dominion.
