The question is whether it is *more* practical than (X)HTML.

You *find*.  What a telling phrase that is.
The plain fact of the matter is that there is no precise
implementation-independent description of Markdown.
We *are* told that [a]  [b] and [a]    (b)  are legal
syntax.  We are *not* told that [a] without a following
[ or ( will be accepted, or, if accepted, what will
happen.  If I should write [A[i],j), will that be taken
as plain text, or will it start with "A[i" and go looking
for something more?

If you *don't* want the documents to be viewed in a browser,
there isn't the slightest *point* in using Markdown.  It
does nothing that plain text cannot do better.

If you *do* want the documents to be viewed in a browser,
then plugins have two nasty problems:  they may not be
available for particular browsers at all (Amaya, Emacs-W3,
iCab) or may have version skew problems (when I upgraded
from FireFox 3 to FireFox 4 a lot of things went away and
have not come back yet).

We had one.  What was wrong with it?

And you can regard a visit to the dentist as a social
occasion.  That doesn't make it a _happy_ social occasion.

No, *PRACTICALLY* it is an underspecified mess of
special treatment for a host of punctuation marks.
I do not regard a notation that I cannot find a clear
definition of as *practical*.  I would have to type
up markdown text with vigilant trepidation, and would
have *no* grounds for believing that markdown text
acceptable to a tool chain I had installed was also
acceptable to yours, especially given that you are
requiring style rules that are not enforced by such
tool chains.

Well, no, I didn't quite say that.  I do _have_ HTML
editors (about 5 of them, come to think of it), but
when I personally write HTML, I find it quicker and
easier to use a text editor.  However, other people
may find it otherwise, and for *them* using an HTML
editor is as easy as using a word processor.

Using say Amaya, the markup would be entirely invisible to
the author.  What a marked contrast to Markdown!

Let's be clear here.
I don't want to stop anyone else using Markdown (and never did
want to stop anyone using ReStructured Text).
What I want is to be allowed to use something
namely plain text.

OK.  Plain text has one problem when viewed in a browser window.
On reflection, I'm almost ready to grant that this is a
show-stopper.  Or _would_ be...  The problem is that when you
make your browser window narrower (so as to view several things
at once, perhaps), plain text is not re-flowed to fit.


Is this an artefact of using Markdown?
It's certainly an inconvenience when using a browser.

I'm not all that good at CSS.  Could it be the fault of
	height: 100%;
in style.css?  I've certainly learned that setting sizes
in terms of numbers of pixels is almost always a Bad Idea.
979px turns up a lot; why anyone thinks that has any
relevance to my screen resolution or browser window width
escapes me.

Netscape came with a built in HTML editor.
SeaMonkey has a descendant of that one.
There's BlueGriffon, which I am about to try.
OpenOffice/LibreOffice lets you edit HTML.
I have a fondness for Amaya.

All free, all easily usable by anyone who has used a
word processor.

The order of difficulty is
(1) Plain text.
    Dead simple.  What you see really is what you get.
(2) HTML, either typed in by hand or using an HTML editor.
    There are precisely two special characters to worry
    about in plain text (< and &) and my editor has a
    single key binding "convert region to HTML data".
    There are plenty of tools to deal with it.
(3) Markdown.  It *isn't* plain text.  It is complex
    and sadly underdocumented.  It is supposed to generate
    HTML but there are simple things to do in HTML that are
    (or seem to be) hard in Markdown.  I *don't* have any
    tools to convert in either direction between plain
    text and Markdown.

Markdown is NOT "just another style of plaintext".
Markdown is MARKUP.  Quirky, underdocumented, markup.

I clearly haven't communicated my discomfort.
It's not a question of how MUCH markup is needed when using
Markdown.  It's a question of NOT KNOWING what is going to
work and what is not.

I see that I shall have to write a 'downmarkit' tool...
