AB ed. These repetative questions, usually from some quiz or about an advert get tedious after a while. I sat and thought about this for a bit then realised that the ask a question is more prominent than the search facility. People are just asking the question straight off, without searching for the answer first. Maybe if the search function was alittle more visible then, we'd have less of these repeat posts.
In response to myself here. I think that this is an excellent suggestion. Especially since the massive influx of people trying to win the radio quiz, which is asking 'what america produces 13 million tons of'.
