No theme's been announced yet (not that anyone need feel bound to stick to one). For more on PAM, see my previous post.
My own suggestion for a theme is, Infowar as Class War. In particular, art has been and is being used to promote the interests and agendas of both rich and poor; and lately, the rich seem to be winning. Forget post-post-modernism; we seem to have entered post-reality. What to do? (More on the current infowar here.)
To get in the mood for PAM, see other artists' and art professionals' written responses to last year's PAM announcement here; they're funny as well as inspiring.
And let PAM's founder, Gene Elder, know what you're planning for PAM, at elder4tomato at yahoo dot com.
