>TeX Computer Modern font...
I don't like some of the design characteristics of
cm. The ff ligature is a little ghastly, and at a
normal pointsize (cmr10) the font is a too `light'
for my taste. I prefer the good old venitian font
families (notice Google uses one of these in thier
logo). It would be quite amusing seeing a complex
math equation typeset with Cloister. I think that
cm is good for math typesetting, but if I am going
to write a letter to someone, it seems too formal.
The reason I suggested Times is because ships with
every OS that I know of. I also hate Times, and I
cringe whenever I am given an article to read that
uses it (when I'm a prof, I think I'll take points
off for using ugly fonts:).
[I actually use cmr on my website, using plainTeX,
dvips, and gimp's ps importer]
