Tex code in TUG page

I guess we can all easily agree that pidgin-TeX is NOT even close to any
ideal dialect to communicate with the blind - the reasons being multiple:

pidgin-TeX is extremely verbose: it takes 9 characters to do bold in TeX,
\textbf{word} while Braille does it with ONE character. A hell a lot more
concise. The rate of tactile reading is proportional to the number of
characters, and as such LaTeX is not used EVEN to represent Mathematics in
Braille.


The drivers that increase accessibility on phones and computers (sound or
tactile) do it by reading text and HTML and they will easily interpret “,
”, —, ... but have no idea what is ``, ' ', \Dash{}, ...

These drivers will read pidgin-TeX like


          \cot{\alpha}


by sounding the entire sequence of characters, which will make no sense for
a non-trained TeX person.


Nemeth is an ASCII linear representation of Math (just like TeX is
another), but one that is very concise and wastes no characters in the
representation.

Bottom line: there should be no space for TeX inside HTML pages, specially
for reasons of the blind.
