Could MathML become like Acrobat? A standard of its own that one can assume people have downloaded the viewer for? Most unlikely, I think. Undoubtedly it could become a niche standard, for which people who care about it have readers. For example, I could put out my course notes in MathML and then require the students to install a reader (if there were one that were managable)*. But is hardly what we want. So I do my course notes in HTML using TtH. [*I mean no unjustified slight to WebEQ, which of course also solves the automatic download problem but at a big cost in bandwidth and usability]. The only reason that PDF somewhat succeeds at being a standard is that is has tremendous breadth. It is not just a niche. It aims at being THE page description standard for the web (as PostScript is for printers). MathML can't hope to compete on that basis. (Although Acroread is so buggy that it seems to me to be in the process of undermining PDF's chances as a widespread standard.) What we want is a standard way that anyone can read our mathematics on their favorite browser, the same way they read anything else. I sure hope that Mozilla will give us that. If it does. Then IE will be forced to compete. Then (and only then IMHO) MathML will become established. And Robert, I have nothing against pointy brackets. I prefer that they refer to quantum states, but I can live with other uses! What I am interested in is stuff that works, more than standards for their own sake.
