If you don't think a node is worthwhile, just don't vote on it. I'm afraid I don't see the benefit to putting this level of selection into the voting system.
If you're one of the first ten voters, your ++<10 vote counts, and then another person votes, so the node has a rep of 11 even though you didn't want to vote it above 10.
On the other hand, if you're the eleventh voter, your ++<10 vote doesn't count, leaving the node with a rep of 10, based on nothing more than the order in which the votes were cast.
This system would make the votes of monks who vote first less valuable than the votes of those who vote later.
