I am interested to see the suggestion that equations are not 
usable when read linearly. I am currently researching this very 
area with regard to equation usage in e-learning systems 
particularly in bulletin boards and messaging systems. 

I have found little research (let me know if you know of some) 
in how students learn the language of mathematics as 
opposed to mathematics itself, and if it is if fact a linear 
process that they use when writing it down, it may be the 
MathML markup language is sufficient as this is what is learnt 
by students when  watching teachers write on OHPs / 
blackboards etc.
