I've noticed some accepted answers with a lot of votes which are strictly speaking not correct, even though they contain a lot of useful information.
Just as an example, the current accepted answer to this question is mostly pretty good however the first sentence is very wrong - a certificate isn't any kind of public / private key pair.
Given that one of the ideas of stackexchange sites is to surface 'canonical' answers to such questions which anyone can find using google, what's the best way to deal with this kind of thing?
comment that the answer is wrong
edit the answer ourselves if we can (even if it's already been accepted and even if it needs a lot of edits?)
downvote the accepted answer and add a new, better answer (even if the existing answer is 90% OK but wrong only in some detail?)
some combination of the above
I realise this is really a question that could apply to any stackexchange site but I guess it's possible that different sites will have their own ettiquette for this, and it's probably worth documenting what we consider to be the 'right way' here anyhow.
Please add your preferred way to handle it here, and/or upvote a solution you like.
