It's also a matter of topic and medium. Technical texts are usually LTR,
literature, newspapers, and magazines are usually TTB.

In particular on the right side of cars, you also find one-line
RTL texts. The best way to think about them is that they are
one-character-per-line TTB texts. Similar things can be found
on traditional doors in temples and shrines. The situation is
similar in Korea, China, Taiwan,..., although of course there
are differences.

I don't do too much surfing, but there are so many English pages
that do gifs for all kinds of reasons that I guess it's not TTB
only that makes them do gifs. You do a gif because you want a special
color, font, placement of letters,... and then why not do it TTB?
Also, there is of course always a trend to try to be different.

The main reason here again is not TTB, but just that the creators
were too lazy to (re)type the whole text, and just scanned it in,
and it happened to be TTB in print.

We haven't completely ignored it! At first sight, it looks close to the
BIDI issue. But on closer examination, it is quite different.
Horizontal vs. vertical is a presentation issue. You can display a
Japanese text horizontally or vertically, it stays the same text.
Therefore, this does not belong into HTML or XML, it belongs into
CSS. BIDI issues, on the other hand, need to be in HTML, because
without some idea of the structure of the text, you have no
chance to get it right in case of embeddings. You cannot display
Arabic LTR on one browser, and RTL on another. And you cannot
have different embeddings on different browsers.

It's not 'ok'. But there are several differences. First, Japanese
can read LTR, and use the web a lot without too much practical problems,
while handicaped people, or people with older equipment, couldn't do
anything with the web without due care. Second, the W3C gets special
money for their accessability initiative from the EU and the US, as
far as I know.

I would really like to start the process, it is long overdue.
I just up to now didn't have the time to do it, i18n for HTML 4.0
(as well as my daily work :-) have just taken too much time.
And there are quite some companies that have expressed their
interest. If anybody else is interested, please let me know.
But it has to go into CSS, where it belongs, not into HTML/XML.
