It seems the recently there has been an increase in down voting on answers. While I'm fine with criticism, I think just down voting without providing a comment on the reasoning is unhelpful. How does the down voter expect answers to improve if commentary isn't provided?
I suspect it may just be because of a small audience. There are always going to be some irrational downvotes, whether accidentally (for example, because they missed the upvote button) or arbitrarily (for example, because you used insufficient semi-colons).
If the number of voters were larger, this wouldn't be an issue, since the genuine votes would far outweigh the irrational votes. But since we have a relatively small audience, this doesn't happen at present.
It seems the answer may be to have more people voting. Easy right?
