To repeat myself and others one more time again (: we should also require a non-blank reason for consideration and should allow a node to be "reconsidered" so someone who notices that a "delete, duplicate" isn't really a duplicate can add a "keep, isn't duplicate" line. This last feature also prevents the "denial of service consideration" which I have used a couple of times (consider a node with a misleading reason and noone can consider it for the right reason).
