A year ago today I stopped work on a web-based trivia quiz that used questions automatically generated from Wikipedia articles. Called WikiQuiz, it let the user choose from a carefully chosen selection of topics, and then would display the content of an article linked to by that topic, but with all references to the article name blanked out. The quiz taker then had to guess what the missing article name was.
The hardest task was to get reasonable articles, ones that were neither impossible nor ridiculously easy. I considered allowing users to rate the fairness of their question, and building up a system whereby the most unfair questions would no longer be asked.
Unfortunately, the WikiQuiz never got to experience life, due to technical restrictions at its live location made just prior to its launch.
Today, exactly one year to the day since I last touched any of the WikiQuiz code, I came across the announcement of a similar venture, WikiTrivia. At this early stage it appears to suffer the main problem that I came across, that it asks quite unfair (often impossible) questions. I hope that it continues to be developed, as I look forward to experiencing the final implementation of the idea I had so long ago, even if it has arrived by an unexpected route.
