An acquantaince of mine, who has one of those office jobs with internet access and a disgustingly relaxed schedule, has developed an interesting hobby: making his own, very "individual" contributions to Wikipedia and seeing how long they remain. He reports a very high success rate - it appears to be a matter of selecting less-active articles and a subtle way of writing (although I think there's at least one county in the USA which now has an elephant park or something it doesn't know about).
