Seeing the web site od dX, I xas amazed by its simplicity and variety.
Simplicity of the signs and symbols used to represent the contents.
Variety of the projects present on the site. The use of symbol looks to me as a very good idea. It defines the Internet as a symbolic space, and opposes it to the exposition space, the "art" space, whiwh is not meant to be symbolic. Signs are maybe a reference to "smileys", but "smileys" are a real net defintion: how to express feelings in a algebric way :-) or :-( . "smileys" are the figure of an old net, not the web maybe, but it could have been the foundation of a symbolic writing and thinking.
In my mind, the Internet is taken in a "18th century" spirit: symbolic, open to the "bel esprit" (which was specifically French: kind of a mean humor: provoke laugh but always on somebody. Use meanless as a fun attitude). Some german philosophers saw in meanless a way to access real thinking, without compromissions or carefulness (Nietzsche).
In a "manifestation culturelle" project, the Internet has a strong status. The Internet is a cultural area. And it makes culture polemical.
What is culture ? An alibi ? Art is not an alibi anymore. "I make art !" "It's a shame". Culture is seen as benefic, usefull, and serving the entire community. Culture is kind of the democracy of art. Its worldwide communication, fragmentation, and consommation.
But, on the Net, culture can have an other sense. Culture is what can be seen of art, what can be accessible, sensible, open, outside the exposition room. It defines an other space. Besides, or outside, the exposition space. In that sense, I didn't like the idea of web projects inside the documenta. The "documenta on line" is a poor "manifestation culturelle" according to me.
The Internet can be seen as another space. It does not have to be used to open the exposition space. Documenta site is what's left after the documenta exposition. What will stay. Culture is what stays. And what has a status: staying.
