I gave this answer to a question. It rapidly attracted a significant number of negative votes and negative comments, to the point where my first reaction was to delete the answer. I could improve it of course, and I did make some effort.
What surprised me is that despite getting so many negatives, I also seem to be getting a number of positives, to the point where my net reputation on this answer is +66. Deleting the answer would be a net loss.
So, what should one do in a case like this? Improve the answer? Answer the detractors? Delete the answer? It largely depends on whether an answer like this is a benefit, on balance. And that's hard for me to assess.
[BTW it would be easier to track what's going on if I could see the votes individually.]
