Interesting, I didn't know that. However, LaTeX allows
writing (and typesetting) math on a "pure text basis"
which may be interesting to authors who are unable to
access a GUI-driven formula editor. Of course there is
another learning courve here. But nothing does prohibit
a blind scientist to write his stuff himself, read it
himself; things as $\bar{x}=\frac{\sum_{i=1}^{n}({x_i})}{n}$
can be quite easily be used if you have learned few
relatively simple things: typing on the keyboard,
using a powerful editor, the "LaTeX language", and
maybe Braille. This way, an author can concentrate
on content, while the tools step into the background
and let him just do his stuff.

As long as the devices play nice... :-)
