An open space for global conversation
Occupying is a means to achieve certain ends. Agreeing what these ends are is the second step. Developing strategies for achieving the ends is the third step.
In my view (from Occupylsx) physical occupation is getting to be a drag on moving forward towards the objectives. The Finsbury Square camp, for example is in a bit of a sorry state physically (ok, partly due to the wet weather). The economics work group is attempting to hold its twice a week meetings on site but even a suitable spot is hard to find for its two hour meetings.
As a movement, we said to the 1 % at the start "enough is enough", referring to the exploitation of the 99 % the 1 %.
However, imposing the consensus rule (too early) on the way the following stages are to be reached may be a mistake. You can not reach agreement on significant decisions if the majority in a assembly does not have the background knowledge about the reasons for proposing a particular action.
Later on, having reached a degree of familiarity with details of the various issues, consensus would be more productive of good decisions. Meanwhile, trusting the "goodness" various working groups (who may have spent weeks on deliberating) would be more productive of progress.
