Macrumours.com is one of the biggest Apple speculation and news communities on the internet. Everyday there are many articles presenting latest rumours, guesses, facts and leaks. These mostly quote a source. One of the 1st comments on any major story is "Can we trust this?" or '[name of source]: in the past they've been...'. A good/interesting thing for the site do would be to, for each article, note the source + their prediction. When the big day comes as well as updating the buyers guide they could check the rumours and rate the accuracy of the sources predictions. You could even account for the time that the predictions were made, and an accurate prediction from earlier on would have yield a greater score. After 1 or to major events there would be sufficient data on all the major sources to use as a tool. This data might be a small icon at the top/bottom of an article that represents the past accuracy of this source. While the accuracy of most sources will vary and not all rumours from all sources are quoted on the site, still I think you would eventually find that some sources are more accurate than others. I know that the history of the source is often discussed in the article, but i'm looking for a quick numerical aggregate score or rank to enable us to quickly formulate an opinion of the new rumour. What would this be like to set up?
