It is not so much that that are too many votes, but that some voters are too indiscriminate.
This was at first a terrible answer, now it's simply not very good and got 5 upvotes ( 1 down by yours truly): http://codereview.stackexchange.com/a/59941/14625https://codereview.stackexchange.com/a/59941/14625 (Sorry Malachi)
We are telling this new user that that answer deserves 4 up-votes in our minds.. That feels wrong to me. We are also telling that new user that his own question ( which must have taken ages to research and write ) is worth 5 points.. (Not too bad, but this is really a nice question, I am definitely going to use that code and it deserves better)
All in all, we should vote more, but/and better.
