This skill compliments you by crowdsourcing material from Twitter. The results could be as simple as "You are nice!" or something funny and unexpected like "Bob is fantastic and I will fight anyone who disagrees!"
For a compliment starting with "You are...": Say "Alexa ask Crowdsource a Compliment"
For a compliment for a friend whose name is "Bob": Say "Alexa ask Crowdsouce a Compliment about Bob"
How it works: The app randomly picks a word from a list of positive adjectives and searches Twitter for tweets that contain that word. It then replaces all the text before that word with "You are" or "{Name} is" to get a random and (sometimes) surprising compliment from Alexa!
