Today, Facebook announced a new feature that might make even the oversharers among us squeamish. It's a feature that taps into your cell phone's microphone, and identifies the TV show, movie, or song playing in the background so you can share it on Facebook. (If you've ever used the popular app Shazam to identify a song -- or seen someone waving their phone in the air at a bar -- it's kind of like that.) It's rolling out on iOS and Android in the U.S. over the coming weeks. (hubspot.com)
