I would like to offer a dissenting view: adding more rep-related info will have the unintended, and undesirable, effect of encouraging users to focus excessively on their nodes' reps. I think the system is already brilliantly tuned as it is in the amount of information it provides and to whom. I wouldn't mess with it.

What I would like to see is the ability to cast a 0 vote that would enable the person casting the vote to see how a particular node is being received by the Monastery (i.e. the node's rep). It often happens that I think a node is mediocre (though not so bad as to deserve a downvote), but I am still curious to know whether other monks share my assessment. Then I'm faced with the unpleasant choice of either down-voting a node that I don't think is so bad that it deserves such treatment, or, alternatively, up-voting the node, which is even less deserved. Being able to cast a 0 vote would solve this problem. I'd be happy to forgo any probability of voting-dependent XP gain from voting neutral, which may be a desirable way to discourage such votes without outright ruling them out (as is the case now).
