Streaming your favorite smartphone apps on Twitch is pretty hard. Through Facebook? Even harder. To simplify the process, Bluestacks is adding a Facebook Live option to its desktop Android emulator. So whether you're using a PC or Mac, you can now grab your favorite games from the Play store, launch them and stream using the same interface. Bluestacks added a similar Twitch-streaming option just a few month ago -- while Amazon's platform is known for gaming, Facebook clearly has similar ambitions. (You can already broadcast Blizzard titles on the social network, for instance.) With so many eyeballs, its influence is growing fast.
