They do it because modern mail software makes that the default. I think
top-posting is a bit distracting, too, but the fault is Microsoft and

The ponies already objected to your preferred range, and I think their
objection has validity. If they find it too hard to find the right
rating between -99 and +99, then they'll consider the method bad however
you put it. Again, RBJ has voiced the same point here on the list:
"Range asks for too much, Approval asks for too little".
You argued in turn that this wasn't so important, and that they could
just not use the granularity if they didn't need it, but that didn't
convince them either.
Thus I suggest that (even if it is your preferred method and range),
that isn't going to work for the ponies. The objective quality of the
objection doesn't matter - it keeps them from using the method because
they don't like using it :-)
And hence I suggested MJ (which works better with few grades, not so few
as to make it Approval and not so many as to overwhelm the ponies), or
Schulze/[insert Condorcet method of choice] if they want ranking instead

There's another point to using letter grades or adjectives instead of
numbers. Doing so shows that it doesn't really matter what kind of
points scale the grades are calibrated to, as long as a majority shares
the same calibration. That is in turn linked to what I said about
monotone nonlinear transformations.
And MJ itself does tiebreaking by providing + and - to the actual grade
returned. For instance, in the 2007 Orsay experiment, Bayrou got Good+
while Sarkozy got Good-. So I don't think the grade inputs should be
given with + and -, because the method appends a + and - to the result
as part of the tiebreak process.
