No, Facebook isn't opening up its live streaming feature to the hoi polloi just yet, but it does have the next best thing. It's rolling out a subscription feature to Facebook Live that lets you know the next time your favorite celebrity starts a stream. You'll have to tap the button on a live video (seriously, shouldn't this always be available?), but it'll keep you in the loop the next time a star has a big announcement or Q&A. Clearly, Facebook isn't worried about competing directly with Twitter's Periscope right now -- it's more interested in boosting the profiles of its best-known users than giving everyone a chance to share their lives on camera.
