Many thnaks Patrick -I looked at your site and enjoyed it very much. Lots of interest there from the point of view of navigation and visuals. Looking at this made it is a lot clearer to me what you were drivinging at.
I really don't have any problem with anything you say. Of course multiple hyperlinks in each lexia of hupertext can be used to create multiple pathways too, but you obviously think that your site creates a different kind of experience, and I can see that in some ways it does.
Anyway I certainly agree that thinking/creating in that kind multidimensional way is extremely stimulating, and I'm definitely interested in those kinds of challenge myself. In fact being forced to think in a multivalent way is probably the thing that MOST interests me about any form of writing!
