Randy's bike has merit; historically, if nothing else. I don't find his bike any more impractical than Safe's or Matt's. It performs well enough, but has room for improvements like any bike.
What is key here, is that Randy's bike does have merit, but it doesn't do anybody much good.
Matt's bike illustrates how anybody can do the same thing.
Swordman's bike illustrates how anybody can do the same thing.
Safe's bike illustrates how anybody can do the same thing.
Jondoh's bike illustrates how anybody can do the same thing.
Knoxie's, Xyster's, Reid's, GeeBee's, Maytag's, Bob's, etc., etc., etc....
The risk of keeping secrets, is that you get stuck in a rut. The rest of the world moves forward regardless of your ideas that sit locked in a garage, when public disclosure could challenge them and make them better. That is the essence of patents: public disclosure. That is also the essence of Open-Source.
So let the talkers talk, and the teachers teach. The difference being, that the teachers are also learners; and grow thereby.
