Quite often I see questions asked that have an answer, but are really the wrong question (bear with me here). "How can I add disc brakes to my $200 bike?" The answer is get a new wheelset and fork, and add some tabs to your frame, sure. It can be done, but really it shouldn't be done (in most circumstances). I've seen this with coding/querying questions as well. Should there be some additional modifier for answers that allows an answer to distinctly denote "you can do X this way [modifier section] this is a bad idea for the following reasons". Theoretically up and down voting questions accomplishes some of this, but it isn't as apparent on some of the lower activity questions.
I think the existing mechanisms work pretty well and don't really require any kind of special modifier...
Typically when a question comes in for something that's a bad idea, you'll end up with:
- A highly upvoted comment explaining why it's a bad idea
- A highly upvoted answer that basically says "Ok, look, that's a bad idea and here's why, but if you're going to do it anyways you should [...]"
Either or both of those are a pretty good solution already.
Do you think people are coming to the site, seeing answers about how to do something that's a bad idea, skimming right past the "this is why it's a bad idea" part and only reading the "ok, here's how you do it" part; and that maybe some extra emphasis on the "don't do it!" part would help?
