I don't think it will be much of an issue. If I were to read something on there that had a chance to harm a system, I wouldn't use that particular advice. It's much like using Google to find an answer to a problem; there is always a chance someone who doesn't know anything about the topic gives an answer that they once heard from a "friend that knows lots about computers." It's always a crap shoot, as a technician you just need to be able to distinguish the good from the bad.
