You have to look at who has the interest in keeping each article edited. Only someone deeply involved in karate will be interested in maintaining karate articles. The same for bicycles, electronics, politics, and pedophilia.
I trust a karate, bicycle or electronics expert or hobbyist to attempt to give me useful information on their hobby. I am wary of the information in political articles because of the neccessary opinion involved in political interest.
Anyone who has the time or inclination to edit a pedophilia article should immediately be distrusted.
"Anyone who has the time or inclination to edit a pedophilia article should immediately be distrusted."
Not really. I envisage such articles would be written by criminal psychologists and pediatritians.
