As Gaming grows, we're seeing a big increase in duplicate questions from new users. This puts us in a bind, because while we certainly want to close the duplicates, doing so can have a negative impact on whether those users choose to continue with the site. It seems like everyone would be better off if we could prevent those duplicate questions before they were even asked.
The "Similar Questions" feature aims to do this, but because it is passive, a new user to the site is unlikely to notice it and/or understand its implications. Could we add something that if there is a question that is very likely a duplicate of the one about to be asked, new users would get a popup indicating that we think there question has already been asked, and linking them to the duplicate instead? (This would obviously be dependent on how well we can detect duplicates automatically. Utilizing the tags on the question would help immensely for sites like Gaming)
