Does anybody have some data on how effective the suggested answers are in preventing people from asking duplicate questions?
While some people make an effort to search, some people will click the "Ask Question" button and will start typing their question. To deal with that SE dynamically suggests to users, answers which match the subject of their post.
What % of people click on such answers (obviously it depends on the quality of the suggestion).
Does it actually stop people from posting their questions (that would probably require an A/B test with two pages, one with auto-suggest on and other with off, so that impact can be attributed to auto-suggest only).
Any other related insights or ideas would be very much appreciated.
