I came across this answer earlier today, which I deemed trivial (all it gave was the solution, not an explanation of why it worked or how to prevent this from happening in the future, and was practically copied from the comments above, which were posted about two minutes before).
I left a comment explaining why I downvoted, and a few people took offense to it:
@RichardJ.RossIII You're downvoting an answer that answers the OPs question? – modifiable lvalue
@RichardJ.RossIII habitually violates the rules. Since this answer is not wrong or dangerous and is in fact useful, it should not be downvoted. +1 to compensate. – Jim Balter
My question is, is there a policy against doing this? Should we, as a community, accept and encourage such answers? Personally, I think the whole question should be deleted, as it is far from useful, but that's not the point here.
Generally speaking, I save my upvotes for answers which either helped me personally, or do an exceptional amount towards answering a question. I downvote a lot, as I have high standards (that's not to say that I'm perfect, however).
The bottom line is this: should I be more conservative with my downvoting patterns?
