I think people want to be able to transmit the same sort of documents
over networks that they read on paper. Documents rendered by Mosaic
are such a leap forward over the old flat ASCII titles with images
as separate titles that our collective appetite has been whetted;
it's not posters people want to deliver, it's glossy magazine
articles with sound and video attachments. It's anything that
you can do on a CD ROM.
So don't look at a poster on the wall as what folks would like to
transmit. Look at the last issue of Byte or Wired, and add videos.
I understand the standard arguments about markup being to denote
semantics not precise presentation, but there's a revolution of
rising expectations here.
