WYSIWYM (What You See Is What You Mean) is the paradigm created for
LyX. It means that the things displayed on a computer screen should
accurately display the information that is trying to be conveyed rather
than the actual formatting.
How that would be helpful in wiki-page authoring, where formatting is
part of the meaning (unlike XML authoring, which is where WYSIWYM
originates).
I am not sure if it is really possible to seperate meaning (list item
number one) and formatting (this is a list item). The user usually has to
specify both, anyway.
One could whip up a JS (think ajax) editor that behaves like word, but so
far I think nobody did it. Probably because in Word, you select a
headline, type the text in, then select lots of styling (bold/color/size
etc), so having lots of fancy options is desired.
) with MediaWiki at some point. I'm
hopeful I can get to work on an extension at some point fairly soon, but
who knows. Sorry for faintly off-topicness. :)
