Right, but of course that's the beauty of it, right? Communal editing (helps) ensures that most errors are short lived. I actually took the effort to edit an article once. It was on hearsay. There were some complicated nuances as between certain hearsay exceptions that the article was trying to clarify. I noticed some errors and confusing explanations, and set about spending a few hours figuring out how best to rewrite that section. Making the changes of course also helped me to learn it once and for all. As they say, no better way to learn than to teach.
