Daniel:
The ArbCom already tries to enforce our content-related policies. What I'd like to do is have subject-area subcommittees to consult when alleged violations of our content-related polices like NPOV or NOR come before us (the ArbCom). As it is, only the most blatant POV and original research-pushing people are sanctioned due to the simple fact that the ArbCom does not know everything about everything and thus can't spot more subtle violations of our content-related polices. We have tried, but this results in cases that take months and inadequate remedies.
I understand that this is frustrating, and it is commendable that you are looking for a solution; this shows that you are indeed worthy arbitrators -- people of action constantly looking for ways to deal with the problems we face. However, I believe that you, Mark and other arbitrators are examining the problem *only* from your point of view as arbitrators. This is an unnecessary limitation of perspective. I think there are community-based approaches that are not as susceptible to error and corruption and that therefore should be preferred.
Now that you have so cogently pointed out the problem -- it's possible to wage "wars of attrition" over articles, and the person first to explode or give up is likely to lose -- I would like us to look together for a solution that is compatible with our ideals and dreams of openness and cooperation in good faith, rather than one that takes us down the road of credentialism and hierarchy. Institutions like the ArbCom, even admins, blocks, page protection, deletion -- these are not perfect and deserve to be questioned and reconsidered. http://usemod.com/cgi-bin/mb.pl?DevolvePower is worth a read.
