It seems quite frequent that a new user will ask their question as an answer to an existing question. Presumably they find that existing one via google and ask in the answer box without really understanding the site.
What tends to happen is they get told to ask as a new question, often it’s friendly and sometimes it’s not particularly. Generally though, it doesn’t get asked as a new question and the ‘answer’ ends up getting deleted.
I assume the new users just think “sod it” and go somewhere else. This can’t be good for the retention of new users or their view of the site.
What if there was the means to have the answer migrated to a new question all of its own, with a link to the existing question for context? I realise it’s asking for a lot, but should we be asking SE for a feature like this? I think it would be far more constructive and welcoming.
