This is annoyingly paternalistic:
Occasionally, you may see "Reputation: 12 (no significant downvotes)?"; this indicates that either there were no downvotes or there was an insignificant number of them. You are not shown how many because focusing on the occasional downvote (per node) is usually a mistake. A node having a small number of downvotes usually has more to do with the person(s) doing the voting than with the node. Such downvotes could simply be the result of a mistake, someone having a bad day, someone's pet peeve, etc.
You used to be able to see the exact vote totals; now you can't.
If I want to know that a few people downvote all my nodes, or that one person dislikes a response I gave (e.g. because the OP found it unhelpful), I should be able to do so. I would prefer that one could see who voted which way on a node, since that would encourage careful voting, but that will never happen here. Still, can we please at least go back to the way it was before?
