As a friar, I believe that removing my ability to vote on nodes to consider is not going to help; the problem isn't to many people voting on what nodes to delete. The problem seems to be too many people nominating nodes to be considered.
I rarely put a node on nodes to consider, but I've been proud of the fact that I finally reached a level that I can provide additional input into how the site operates. I believe a much better approach, if this road is followed, is gradually introduce these new powers so as to teach the rising monks what should be on the nodes to consider before they can the ability to put them there.
This might be as simple as giving the ability to vote on nodes to consider at level 6, but not allowing nominating nodes for nodes to consider until level 7. This would give friars the opportunity to participate in the running of the site while still emphasizing the concept of more responsibilty as you increase in rank and teaching what is the commonly accepted guidelines for nodes to consider.
I also feel that allowing lower ranked members to view the nodes to consider node, without voting, is something we should consider. This would be similar to how novices are not allowed to vote when they first join, but they can see how voting works.
