con? mathml is a *standard* for representing math on the web, I'm
really not shure how a standard can be a conn since the authors won't
make any money from the standard existing or being implemented.  If you
want to say that math player is a con that atleast makes sense, but never having
used math player I won't comment on the claims accuracy.  However I will
say that it is  very unfortunate that we can't access mathml content in
any webrowser that can render it the same as sighted people.

 The point is that LaTex is not the format that you really wan't to
 recieve math in, and as a blind person I agree, it often works, and
 there is often no better alternative, but its not wonderful.  When I'm
 reading math I don't want to have to filter out formating commands and
 look up other people's macro definition just so I can understand what
 they are saying.

LaTex is an _type_setting_language_ not a language for communicating
math, so he wrote the LaTex that would produce the formating he wanted.
Note that this also proves his earlier point that you really don't want
to read laTex unless there is no other option.

The point is that it would be hard to read, and that's true there is
complicated LaTex out there, and it is hard to get the content out of,
its do able but its not trivial, and a waste of your time.

I would disagree, reading alt tags for images is particularly painful
because some screen readers can only read the whole tag in one shot, but
There is also the issue that LaTex just isn't the format you want to
read, it contains a lot of formating commands, that help you understand
nothing, and consume cycles that could be spent on something useful.  So
while I need the information and can get it from raw LaTex on wikipedia
I think that I _have_ to get it that way sucks.

yes, and they use it as a format to _write_ math not to _read_ math.
You will not that most people make available for reading the pdf they
produce from LaTex source not the source itself.  So you can see that
infact he is correct most people would prefer to read something other
than raw LaTex.

math player may be buggy, I have never used it and have no idea, but it
is only one tool for using mathml.  We can and should have better tools
for getting access to mathml, particularly web browsers should directly
provide the information to screen readers.

I agree, I'm not sure that mathml is the best answer, but if we can get
good support from web browsers and screen readers it should be much
better than reading raw LaTex.

I'm not sure of the details here, but it may also be the case that it is
good to know LaTex so that one can accessibily produces documents such
as home work and papers.

yes, but given the current state of the world I'm not completely sure
that websites have a better alternative.  What I men is that if a
website uses mathml then currently you _need_ windows and internet
explorer and math player and jaws to access the content.  Providing both
LaTex and mathml helps this alittle.  On the other hand having a lot of
math on the internet that is completely unusable because mathml is only
accessible with one tool chain might cause other browsers and screen
readers to start working with mathml.
