Anders at Surftrail delivers a thorough description of where he has erred when introducing us to Espen Aarseth and Mark Bernstein's views on hypertext. That was a very interesting post, Anders, err again, will you please?
As for scientists who write about hypertext in hypertext, I am very curious about my colleague Anne Mangen's work in and with Xerox Park's hypertext - or is that elastic text - FluidReader. This fall she expressed a desire to write her thesis in Fluid.
I think Fluid is quite a bit better suited to this than the MUDs I fantasised about using for my writing, some time back in 1998... Writing a Ph.D. as a game would have been fun though!
