I would add that people should be careful with their considerations. ysth is right, precision is important. There have been many times that I've voted 'keep', not because the node shouldn't have something done to it, but because the consideration is too vague, too off-the-mark, or not the appropriate action.

A node can only have one ongoing consideration at a time. If someone creates a lousy consideration, it prevents a well-done consideration from being made until the current consideration is unconsidered or finishes its voting process.
