I wasn't referring to WYSIWYG actually, but WYSIWYG would certainly be
nice. There is nothing inherent wrong with WYSIWYG, but with the
artificial limitations placed on it.

WYSIWYG doesn't have to apply to explicit sizes. It could work for
proportions and in some applications it already does. Take for example
an application that allowed you to style a canvas into areas. In one
direction, character-flow (the direction the character is next is
displayed from the stream) you could only provide percentages of the
viewport. So one area would be 25% and the next would be 40%. It would
be easy to see when it adds up to 100%. If it doesn't add to 100%
issue a warning.

In the other direction, line-flow (the direction the next line will be
placed), you specify lengths in lines (with auto being an option to
display as many lines as it takes).

You wanted examples, here are some.

The working group shot itself in the foot by giving authors the tools
to abuse the language. Of course they're going to use WYSIWYG tools to
produce pixel perfect layouts... That's what's easiest.

If you want a person to go a particular way, make that way the most
desirable for them to go. Users to me work a lot like water. They
often follow the path of least resistance whenever it comes to things
unfamiliar to them. Then once that path is established, they don't
change. As they use a particular path, they reinforce the tunnel
provided. So if you're going to provide an alternative to an
entrenched method, you're going to be fighting uphill.

Isn't it good that usability gives us the tools to quantify. User
studies, tests and statistical analysis all provide the means.

My statement there made no statement as to whether or not CSS was easy
to write for. That is the point of the post, but the point right there
was to say that designer's should adjust for users not the other way
around.

Because of what I do, I work a lot with the IT techs in my company.
They offer valuable insight into what is being asked repeatedly. As to
the God-given right argument, it is the hope of every company that
they see the greatest penetration of their product. While they know
not everyone will want it, they would probably be pretty happy if
everyone bought it. Don't confuse this with the tactic of making
something rare in order to make it more desirable. This is a marketing
tactic. They still want as many people to buy their product as
possible.

Designers aren't end users which is why if you want to be successful
you get someone who knows users. Usability specialists are those
people. Also having an end user on your design team can help if you
know how to get accurate information out of them. User-created design
isn't usually very good.

I'm just glad most company's don't take this same attitude. Could you
imagine car companies that decided you needed to have a certain talent
for driving in order to drive. Most would call this elitist and I
would say they were right.

And head over to the HTML camp; it was designed so that it could be
used by everybody. They can chew you out.

I'm thinking you misunderstood something. I was saying that people who
post here have been using the CSS box model so much, that when they
think of layout, their own internal model is heavily influenced by the
CSS model.

I have before in other posts. I usually post some idea about every 2-3
months. Above is a smattering. But beyond that it's not usually the
job of a usability person to design, it's there just to comment on the
design and to provide guidelines. If the design doesn't meet the
guidelines it should have a good reason why it doesn't.

I do by the way, but I work it from all angles. And how does blaming
Microsoft help you? I'll leave it at that.

I don't know how many times I can specify how I would change it. If
you're looking for a written proposal, that I haven't done, but I have
submitted ideas consistently.

As for the stand that I'm arguing for what I want, I'm not. I'm
arguing for what I feel users want based on user studies and
observation of users. My use case is completely different. I'll see
about putting together a proposal, but don't wait for it to start
discussing alternatives.
