@joepie91 even in magic forums, where the name of the game is gatekeeping knowledge so that layman don't catch on - there is still a way to be helpful: "well if you can't figure that one out on your own, maybe try reading Bobo's" or "Pick up Tarbell volume 1 and pay attention to Lesson 5, then come back"

Both of these are, in the digital age, kind of rude, you're essentially telling someone to read a book for the answer to their question, or worse to gain an understanding of why they don't know the answer to their question. It definitely gives the expert a feeling of superiority, but it also provides direction to further someone's interest in the hobby.
