Anecdote: I've discovered features with Alexa on accident before. I was watching Jeopardy at my parents house and someone yelled that Jeopardy was on, and Alexa was like "let's play Jeopardy!" and booted up a game for us. I would have had no idea that Alexa could do that if it weren't for the fact that it's.. uh.. constantly listening to everything that goes on in your house.
