Temporal hypertext
Thoughts on hypertext and time extension (continuing a discussion between obvious and meika):
Instances of hypertext are time-extended, of course. Wikipedia is always changing, different now to how it was and will be. However, that is not temporal extension represented to us by the medium; rather, the medium is time-extended along with us, so we see subjective moments of it. That is, Wikipedia, now, is not a representation its temporal progress any more than I am a representation of my own temporal progress.
All material things are temporally extended, but some representations have temporality built in. Film, for instance, is temporally extended itself, and uses that property to represent temporally extended things. So as I see and hear a seal barking at the cinema, I understand that temporal progression using just the same faculties that I use to understand real seals actually barking. (This line of thinking I associate with Noel Carroll, although I actually read it years ago in this book by Gregory Currie. [In keeping with the mind-mapping theme, I have left in my Google Books search string for your enjoyment!])
However, in film, as in comic strips, our interpretation of the time represented is dependent on some conventions. For example, the next scene might be only a second away, but represent events three weeks later than those represented in this scene. (You may even be lucky to have such realistic temporal ordering - consider Pulp Fiction, or, preferably, another more arty film that used temporally disjointed narrative before Pulp Fiction and makes me seem cooler to you for having referenced it.)
So there's temporal extension like film's, which is part of the medium and of the representation, and there's temporal extension like painting's (or comic strips'), which is part of the medium but not the representation. That is, a painting is all there now, but you can read time's passing off it. A film is only partly there now - just like the periods of time which it might represent.
I think hypertext's temporal extension is more like that of painting than of film. However, one thing that is built into hypertext - that is part of its representation and its medium - is sequence. I can dictate that you must see this page before the main site, unless you click another link, which I may or may not give you. Navigation around the overall map is not totally free. We have to follow the links; we can't just warp around the place. So ordering is built in, which is a key part of temporality.
(So what does this link mean?)
For meika and obvious: back to the discussion
Edit (October 2008): This discussion actually ended up continuing through the comments on this post. (There's basically two whole other posts in there.)

A palimpsest is an interesting case because all the information is in the artifact at once but it cannot always be experienced in one instant, as a painting can, in principle. (It is like the reel of film in this respect.) Some palimpsests, like the gable end of that building you showed, are like a painting: all the remnants of layers - all the temporal data - are there at once. In contrast, the different layers of a palimpsest like the Picasso one you pictured must be experienced separately - you either look with your naked eyes or with an x-ray; you can't do either properly if you do both at once. So there can be separation (the impossibility of co-perception) of the layers of that palimpsest built into the medium of representation, and the same separation of the things represented. The palimpsest then can realistically depict the impossibility of co-perception. (I think I am using Currie's terminology there - see the link below.) That impossibility of co-perception - of two events, say - has a part to play in the notion of order or sequence, which I already said was a key part of temporality.
