The other problem I have with community cooking websites is that usually people always underestimate the cooking time and that's annoying as hell. Like people would say you need to cook onions for 10 minutes, while onions take close to 25 minutes to be cooked. On the French website marmiton, it was so ubiquitous that they have moderators come in and fix people's recipes.
