I was the one that started that.
It was a very bad attempt at getting some attention from some of the users that do have close vote privileges but look like they're jumping on every question as soon as they're asked to answer them
Basically, I wanted to do something to get their attention and get a sense of community going here. To me, at that moment, it looked like there were two completely different communities on IPS, one answering questions as soon as they come up without regard for whether it's a good question or not, the other trying to get this to be a quality site.
Don't worry, you're not the only one that thinks this was a bad idea, I do realize it was a bad one myself now too. So, there's some better guidelines on how to reach out here: How to get a better sense of community going?. Like Jesse commented, a very interesting read, I'd really like you to read it through and if you feel like contributing, if you have any other ideas, please feel very free to put them there :)
Note: It still IS a bad idea to answer questions that don't meet the site's guidelines (off-topic, too broad, opinion based, if it should be closed, it should be closed, it's a low quality question that you do not jump on to answer).
The point of the comment was to point this out to those people writing answers. That it went pretty bad is my fault, I'm too impulsive perhaps. But when a question is answered, it doesn't really provide an incentive to an OP to better their question. As proof, have a meta:
Also, take a look at how many questions are currently on hold. Many of them have 1 or 2 answers, some even have 5 or 6. Others even have accepted answers. Now, try and find one where the OP provided us with information to improve the question/edited their question themselves.
If answers are getting upvotes this will encourage users to just keep jumping on every question they find, because hey, it does give you some reputation! There's an excellent answer on that same meta on how we need more high-quality questions for those people to answer, so that need disappears. I fully agree with that.
As for the downvoting, I don't think that's necessarily bad. The answer might not answer the question, might not be about Interpersonal Skills (which makes it not an answer on this site), is being way too liberal on interpreting the situation, or problems like that. EmC provided a better approach to the whole thing here though.
I'll put a small part here:
Personally, I'd comment and possibly vote on these answers. I often just don't vote at all, as I prefer to downvote answers on their own merits, rather than the quality of the question, though how you use your votes is up to you. If the answer was hasty and there was critical information missing from the question, there must be something not considered in the answer (else why close the question?). E.g, "The OP never specified this was their goal. Please note that the question has been placed on hold since you answered - you should consider removing it until after they improve it to give sufficient detail about what they want to accomplish, as it may invalidate your answer and attract downvotes."
Personally, I'll keep this in mind. If there's answers to questions that are put on-hold, I won't be slapping a stock comment on them anymore.
