First, it is your responsibility as a learner to decide if something makes sense or not If one doesn't know anything about a topic and comes across two tutorials - one written in broken English (because the author is not a native English speaker) but the steps are accurate and other written in perfect English but the steps are wrong, it is highly likely they'd pick the latter. That is just one example. Often, it isn't easy for beginners to tell good tutorials from bad, especially for highly technical topics.
