3: If there are multiple valid solutions to an exercise, list them. If some solutions are better than others, explain why. If there are solutions which are technically invalid but commonly thought up by new programmers, explain what they did wrong. I would also add a forth point: "Overdoing the 'lol im not like those nerdy others programmers, im a regular normal person like you' rhetoric. Instead of mentioning an old cliche (and then trying to distance themselves from it), why not just not mention it at all?
