I think that multiple votes to frontpage an article would be a good thing, though I would tend towards more simplicity in the implementation: the node would be frontpaged only once 5(?) friars+ had clicked the checkbox. This would avoid having positive and negative frontpage votes, etc. I think if five senior-ish monks agree on a node's worthiness, it's probably worthy.

The number five was chosen as the number of votes needed to delete a node. Of course, frontpaging could be made entirely analogous to consideration -- a node gets frontpaged if it has at least 5 front-page votes with no more than 1 "leave it off the front page" votes. This adds another level of complexity, though.

Or frontpaging could be moved up to be a higher-level power so that the bishops would feel important...
