user4108: The issue
I have been bothered for a while now by this answer to Why do men have nipples?.
As @Corvus and I mentioned, the answer is misleading and IMO and arguably, incorrect. However, the answer received 24 upvotes and 5 downvotes. I would assume that most of those who upvoted have little reputation associated with the tag "evolution", while those who downvoted have higher reputation associated with the tag "evolution". I suppose, we have a case where the ignorant majority has more impact than the knowledgeable minority.
Question
Should we do anything for this answer or is the majority always right?
Can we do anything for this answer?

user16651: Actually, while I wouldn't necessarily say that the female body plan is the template, there could very well be more to that answer. If the cells that differentiate to form the chest (for simplicity) are set on their developmental path prior to the expression of SRY, then that is the answer, that the body plan is gender neutral up until the expression of SRY, and therefore, all of the related architecture that lead up to nipples is in place prior to sex trait expression. 
That SRY acts to suppress the further development of more prominent breasts, functional mammary glands, increase in areolar and nipple size and enervation  that actually allow for suckling of the young, at puberty, doesn't mean that it will delete them from the body plan of males all together. You are not going to get genetic drift in males because you aren't losing the selective pressure on the species as a whole to maintain breasts and nipples in mammals. We have infants that are born with digestive systems and immune systems that require time to mature and need the nutrients, antibodies, and microbes from the skin of the mother while that maturation takes place.

user1590: I think there is another example of the wrong answer getting highly upvoted (& accepted) in this question, which got on to the hot network questions (HNQ).
I made a meta stack exchange post about it to seek advice because I've exhausted the normal routine. At the end of the day, the post does not answer the question. It got massively upvoted because it is, nonetheless, an interesting post (it deals with a different question, see my comments on the post). I believe it got upvoted so much because of being posted quickly on a HNQ, and suffered from voting bias (people see it is upvoted, assume that means it must be a good answer, and add an upvote themselves). The post is interesting, hence it gathered some upvotes, but if one actually critiques the answer, they would conclude it does not answer the question.
There is a normal routine to follow for bad answers:

Downvote and comment (request improvements, highlight the problems)
Post an alternative answer

However, as a community I believe we should be going one step further - flagging or deleting such posts. This is because (as demonstrated by the post that I have highlighted) downvotes and comments can be ignored, and it is unlikely to "overtake" highly upvoted answers by posting an alternative later on.
Personally I feel that if the post fails to address the question which is being asked, then the user has not attempted to answer. I'd say this qualifies for flagging as not an answer: while the post may be interesting, it is not a relevant answer for the post and should be removed by the mods. 
Likewise, if we are allowed access to delete votes (>10k rep?), then we should be voting to delete. 
Another alternative is to post the question the user does answer and ask them to transfer their answer, but I don't think this a good alternative - the user who posted the answer is unlikely to be tempted to delete their big rep earning answer.

user4108: Following the first part of the above @fileunderwater's comment, I posted an answer here on Why do males have nipples. I made it a community post (thanks to @fileunderwater's help).
I suppose that we will fail to bring this answer to a significant number of upvotes. Also, because the OP hasn't been active since almost a year, (s)he will probably not see this new answer and will probably not change the answer that (s)he checked.

user810: OP here,
First off, I HAVE NOT FORSAKEN YOU (as another answer suggested)
But I have taken a bit of a leave of absence. The sudden flurry activity on this question has brought me back. So…
Why did I accept the currently "accepted" answer?
Well as has already been pointed out, there weren't any other high quality answers to the question:

The most upvoted answer mentions something about how "the female body plan is the default one", which is a fun sound byte but not really sound logic. I'm happy to go into the details as to why I think this is logically flawed, but hopefully it's clear to anyone reading this. In any case, I couldn't just leave that answer on the top to gather upvotes.
Several other answers were just random (vaguely sexist) conjecture.
I'm a physicist, so I'm cool with logic and math and stuff, but I honestly didn't know of a better term than "neutral theory of evolution".

I like the community wiki answer. I don't really like introducing mathy terms like "coefficient" and then explaining them vaguely (again I'm not a real biologist), but otherwise I think it's a great answer.
