Aaron Rester explains why web sites that respond to and enable the collective activity of their audience are less likely to become occasionally noticed but little-used monuments:

Just as Lefebvre leads us to see built spaces not as the expressions of a single architect, but rather as the production of the wide variety of human interactions that occur within them, so websites created by cartographers would cease being grand edifices of unidirectional communication and become instead the collective product of the individuals whose lives intersect within them.

The rise of the social web demands that if we are to help shape meaningful online experiences for our users, we must rethink our traditional role as builders of digital monuments and turn our attention to the close observation of the spaces that our users are producing around us.

I think this is even more true for internal websites, i.e. wikis. Most intranets are “grand edifices of unidirectional communication” whereas wikis can be precisely the opposite, if structured and introduced appropriately.
