actually....
success=market domination is the argument (not mine) from which I started replying by writing the post.
Later on, answering that other comment, I replied that dumb statement like that one about PDFs being enough, are what prevents ANOTHER, really different type of success, which has nothing to do with market domination of any given software or sw development model, or markets in general. The success, that is, that society achieves as a whole, from a civil rights point of view, when open digital standards become the default.
I agree that the two things didn't come out very well separated in the flow of discussion. Thanks for helping me to explain this.
