Please elaborate on the source of the disconnect for you.

Perhaps I failed, but I tried to make it clear that the foundation of great marketing IS building a product the market needs...because doing that well usually means knowing what the market needs in the first place.

Knowing what a market needs and understanding those needs all the way through is exactly what I mean by "marketing."

Once you understand the substance of that argument, the ideas that Google Wave failed because of bad marketing and that building a product that the market doesn't want IS bad marketing make a lot more sense.
