If I see the following in an answer... What should I do?
Since I'm the offending party this is going to be lopsided answer of course, but here are some thoughts.
The question that I'm linked to is extremely related. They are both about race conditions seen in producer/consumer threaded application which I have a lot of experience with -- you can check my SO multithreading and concurrency scores if it makes any difference.
I actually created a web page to specifically address the incorrect answer and I read pages on meta at the time to see what I could do to counter the example in question. I added comments to it. I pinged the OP a couple of times. Didn't make much difference. The wrong answer continues to get up-votes and my correct one is below the fold.
Take note and use it as a strategy for (gaining precious reputation) correcting a failure in the community to identify the correct answer?
I would love to have my name (and related reputation points) removed from my answer if it would mean correcting the page in question. This is certainly not about "gaining precious reputation".
Now we come to another question which is also specifically about the same topic. I answer it fully with good detail and examples. And I ask people to "please consider" voting on the other page with the wrong answer at the bottom. Why is this so wrong? I'm making a polite request after taking the time to inform the reader about the same subject.
I guess I should live with the face the SO gives wrong answers every so often but it's depressing.
Edit out the text?
I would never consider editing out a section of a guy with more reputation than I. I would certainly comment on it first which I guess is what you are doing here.
Couple months later I have toned down my request at the end of my answer to not encourage downvoting -- that was inappropriate. But I still encourage people to upvote my answer which I still strongly believe is much more relevant to the question.
