  I have all the time spoken about the math fints issue, where you always
tend to run out of symbols.

  Are you discussing the text fonts all the time? :-)

  I knew intuitively that optical scaling is important in math, especially
for all those scriptsscripts, which it is really nice if you can use
without restriction in a math paper.

  Michael Downes made this precise, by remarking, in effect, that it makes
only a difference for those scriptscripts (if your paper is in 10 pt);
otherwise not.

  It makes any difference, I did not know this, so I fekt it was very
interesting information myself.

  In general, I try to avoid polemics, so even if I put up some stuff, and
somebody would misunderstand what I try to say, and puts up a polemic
"correction", I would normally not bother following up on that. :-)

  Basically it is what facts come up in the end, that is important.
