Members are asked to look for previous threads before starting a new one. Depending on how general the topic is, the number of such threads may be anything from zero to several hundred. (I think the maximum number of results is approximately 1000 threads.) Ideally we're able to refine our search so that the number of results is not greater than what is practical in order to solve the query at hand. In practice - at least that's my experience - it happens not seldom that the number of threads to choose among is so great that the effect is discouraging. In those instances, I feel the problem is that we have no way of evaluating beforehand what's hidden behind each hyperlink; we have to open them, one by one, to find out about their quality, or applicability. While it is an advantage to have access to a vast amount of information, if we have insufficient means for discriminating among its pieces, and therefore choose not to make use of it because of the time investment required, a part of its value is lost. What I wonder is: 1) Am I alone in experiencing this as a problem: to have no means of discriminating among previous threads when there are many such threads to choose from? 2) If not, would it be possible to add to each thread a question asking the reader whether the information was useful, and present the frequency results of the responses along with the list of threads in order to make it easier to choose a relevant one?
