There is a conference in San Francisco about 'web 2,0' . Not sure what this involves but I am having a look as stuff becomes available. It has been going for a couple of years but I only found it recently.

There was a link on the Seybold site that turned up as Seybold Seminars were cancelled for New York and San Francisco. Medialive are now working with O'Reilley on this new conference.

I found an article by Tim O'Reilley explaining web 2 and this includes two coloumns of the old and the new. So 'publishing' is old and 'participation' is new. Presumably this means publishing as in chunks of knowledge as in books or static web pages.

I don't think Seybold was just fixed on that but the origins were in digital typesetting. I don't think this has gone away but there seems to be a major move in San Francisco.

One strange thing is that Adobe seem not to be there much. They came to dominate the previous world of Seybold and Adobe Live took over in soime ways. Maybe Web 2.0 works better with a wider range of companies so there is a better discussion.

Macromedia are still there. More news coming out so things could be clearer later.
