If this was a small project just starting out, that would be a valid suggestion
(but a poor one; a paragraph should hava a tag just like anything else).
Given however that the Web is in daily use by millions, such a suggestion is
well off the mark.
Yes, there is a problem in that <p> has no </p> and is at the end of a
paragraph. OK, its broken but the browsers handle it.
They also handle a form which fits in with the way all the other tags work:
<p>this is a paragraph.</p>
and this form is likely to be in html+

Absolutely.

This is confusing several issues. Yes, HTML should be frozen as a standard
rather than continually being twiddled with. Hence HTML+; what was learned from
HTML has been fed into it.
But altering HTML at this late stage to be even less SGML compliant would be
such a bad move I am amazed that anyone has suggested it.
Incompatibility is a non-issue; I suspect a browser can tell the difference
between text/html and text/htmlplus.
Now is indeed the time to consider such changes; the defect has been noted and
corrected; the HTML+ DTD specifies <p> ... </p>. Simple, consitent, SGML
compliant. End of problem.

Indeed.

Why?
And why just lists?
And why LaTeX of all the awful things to pick as an example. If you are happy
writing in LaTeX, do that - and use the Leeds converter to make it into HTML.
But do not suggest that HTML be altered in wierd and un-SGML-like ways to fit in
with what you happen to already find familiar. Not everyone uses LaTeX; and as
the Web grows outside the research/academic community, the percentage of LaTeX
users will fall drastically.

I think this is just saying that the suggested "empty line means a closing
paragraph tag really" method is just not SGML and would need unsightly hacks to
express in in a DTD. I agree.

You think that having a blank line mean something in one place and not mean it
in other places (lists, whrere else) is 'convenient to use'. Come to that, you
think that anything connected with LaTeX is convenient to use? An even bigger
mistake.
Count the number of people using LaTeX in 'the real world' compared to the
number using GUI wordprocessors.

No, it makes it something which is consistent with the way all the other tags
work and is therefore easier to use and understand if you are typing in html by
hand - which is not the only way to do it. How 'onerous' is typing </P> ??
You will be suggesting next that titles are well handled by a text editor
This is a title
---------------
so that should be in HTML too? ;-)
>no one but a parser-writer

So you want to do away with <li> too? How does LaTeX do that then?
If people understand that <h1>Title</h1> is a title, understanding that
<p>paragraph</p> is a paragraph does not seem too great a leap.
I think this thread has conflated several distinct points:
1) Current usage
Current use of the <p> tag as a separator is anomalous. This has been sorted in
HTML+
2) Ease of parsing
Having a consistent, SGML compliant syntax makes documents easy to parse and
generate automatically; altering the spec to allow non-SGML-like forms would be
a backward step.
3) Ease of use
People find easiest using what they know already. People used to LaTeX naturally
find the forms of that mark-up more natural. People using other things will find
those things more natural. The solution to this is not however to turn HTML into
LaTeX - which which would only suit one subgroup of users - but to author using
a system you are familiar with and convert or export as HTML. Solutions already
exist for LaTeX, FrameMaker, Microsoft Word and WordPerfect. There is a project
to develop a Motif GUI html editor. Ease of use is addressed by better
HTML-producing tools, not by convenience hacks to HTML.
