Steve Shillingford joins us to chat about his new app Sudo, which puts safety and privacy back in your hands thanks to on-demand phones numbers and email addresses. Plus, @Brittlestar is back to talk about Musical.ly and why your pre-teens and teens can't get enough of growing community.  We also chat with Beddit about how their sleep tracker measures your rest without disturbing you.  In Socially Speaking, we discuss why a robot kill switch is the next must-have tech.
