The use of repertory grids in web-art analyze
In this world we always use categories that help us make it simpler and fit
into a certain understandable system.  Like rods can form a grid, some of
these categories interlace to form structures. Through these structures, or
grids, we see the world around us and create things (be it scientific works,
pieces of art, or whatever). Now when we are at the outset of mastering the
hypertext culture, we need to collect as many constructs as possible, since
without the rods as the basic elements of culture no grid at all can be
built. For better education it is necessary that the mental constructs used
by experts be clearly understood by the others. This is where the repertory
grid techniques will help us. By way of elements we took several web-sites
from da-da-net festival. 
Experts are asked to classify these sites, giving each a description in
the terms (constructs) of his/her choice, and ranging the sites relative to
every single construct.  It is supposed that every time, a method can be
offered to an expert which would let him/her see the films from a different
prospective, and thus produce a different classification of the same sites.
Running this procedure several times yields a collection of "rods" that is
in real use by experts.
