I'd like to have some discussion of hypertext models (such as Dexter) and
an explanation of what open hypertext is.  Since those questions aren't
asked (or answered) much I guess those sections can wait.
  Wikis and other collaborative writing environments deserve serious
attention here.  The section about mailing lists should be updated to point
to Wikis too.
  There needs to be more about the role of the WWW (as a hypertext system
and an enabling technology).  Some discussion and draft Q&A appeared in the
newsgroup in August 2002 and 2003.
  The part about non-linked hypertext needs more details.  An early draft
was posted on 13 August 2002.  New notes appeared exactly a year later too.
  Some URLs need updating and some need replacing.  The HCI section in
particular needs work.  Postings from early August 2002 contain the new
URLs.
