We are trying to make the experience for new users one that is as positive as possible, but we are also concerned for the quality of this site and the value to its community.
While new users of course are important to us, we don't want to be too lenient and let site quality drop. This might cause a broken window effect, we strive to avoid.
I currently only see 3 of your answers on your profile, and from those, one is rather exceptional, in length and quality as in appreciation by the community. One is +/- 0 without comment, which is unfortunate, and one is rated negatively with a longer but not really productive comment thread. The latter is unfortunate as well, but can happen. I personally don't see anything wrong with your post, but others seemed to disagree.
I think the biggest negative factor there was bad luck, as your post might have drowned it older, highly-rated answers and only those thoroughly reading (and downvoting) everything may have gotten there. Or maybe people didn't agree that your answer adds value over what had already been said. It's hard to tell and I hope that you don't take too negative a feeling from this. It happens.
You will also rarely get real feedback from downvoters. Some users are thorough about it, helping you improve, some just want to weigh in with a vote and probably hope that somebody else that agrees with them will point out what they found wrong.
Taking it personal
Please try not to take any downvotes persona. I'm aware sometimes they may be and sometimes it is hard to bounce these things off. I hope with time, more positive feedback will make this much easier.
I hope to guide everybody who feels feedback (or lack thereof) affects them negatively to our chat, to take this up in direct conversation. Even the most active people miss things and can't weigh in everywhere, but we usually linger around the water cooler, happy to talk.
