Forwarded below is a message from Damian Stewart. What he talks about is
one facet of a bunch of issues for media practice.
To my mind the biggest 'problematic of practice' is that work exists
primarily in documentation: that the immediacy of experiencing a work in
person becomes secondary to the quality of the documentation. Which
means, that both a) having a nice camera and a good eye for film editing
techniques (or budget to hire someone who does) is more important than
the actual work itself, and b) works that film well get more exposure.
