Bruce Mau's Incomplete Manifesto has some really nice elements. I particularly like:

No.3: Process is more important than outcome. When the outcome drives the process we will only ever go to where we've already been. If process drives outcome we may not know where we’re going, but we will know we want to be there.
No.8: Drift. Allow yourself to wander aimlessly. Explore adjacencies. Lack judgment. Postpone criticism.
No.14: Don’t be cool. Cool is conservative fear dressed in black. Free yourself from limits of this sort.
No.28: Make new words.Expand the lexicon. The new conditions demand a new way of thinking. The thinking demands new forms of expression. The expression generates new conditions.

Another idea for a semi-automatic manifesto: harvest, edit, re-write: find elements of previous manifestos that strike a chord - re-use, revitalise! A global/historical/collective manifesto of the greats.
