Nintendo's new Miiverse social network for the Wii U can be helpful when it comes to other players sharing game advice and protips, but just like any other informational resource, you have to consider the origin of the information and judge whether or not it's trustworthy.  Not all help is good help.  Mario learns a hard, hard lesson in this Brawl In The Family comic when he fails to verify some New Super Mario Bros. U Miiverse advice before acting on it.  There's something about Nintendo's characters being able to read the Miiverse messages that I find hilarious.  I never considered that they may be able to write those messages, too.
