Periscope for Android lets you broadcast live video to the world. Going live will instantly notify your followers, who can join, comment and send you hearts in real time.

I’ve used the Periscope app, and it’s actually very well done. It’s just that there's a ton of content there. Periscope would be reality TV if reality TV were real. That said, it's something for Twitter that no one else has; until the idea gets copied, of course.

That said, there’s a ton of fun things to watch here, but it can be hard to find the good stuff. Obviously, your best bet is to find people to watch by who you follow on Twitter.
