Mark Zuckerberg: "There is also an element of just following attractive people... for the long tail of gawking I could definitely see people spending lots of time browsing public Lives of people of their preferred gender/age around the world. And it wouldn't be creepy because the people broadcasting explicitly want to have people watching them."

"I'm excited about pushing ahead as fast as we can on Live because it is the most unique and promising new development in two spaces we care about deeply but are behind in: video and teens... This can be the beachhead we need to expand into other use cases in video and teens." "Ramp up push notifs and NF ranking. If we want to grow reach, these seem like the two biggest levers we have. we should prioritize them to have this widely rolled out by the end of March." "Public figure incentive program. When we do our launch, we should have many public figures -- especially teens -- ready to start producing content." "I think it would be reasonable to spend $100-200 million per year worldwide on a program like this to start. This would span teen celebs, YouTube/Snapchat/Vine stars, other already prominent figures -- and ideally people who aren't strictly media entertainers, like athletes, journalists, scientists, doctors or even politicians if we can figure out a way to do that." "First, getting notifications, badges and the UI around subscriptions right is key for engagement. I'm assuming we'll notify you and badge the tab whenever someone you're subscribed to (and we think you'll be interested in) goes live. I'm also assuming we'll automatically subscribe you to your friends and everyone you follow, but will have to algorithmically prune some notifications to prevent people and especially pages from using this to spam. These notifications and badges will be critical for engagement. The notifications will let people know they can tune in now. The badges will last until you visit the video tab, so they'll also surface recent Lives that are no longer currently active as well." "Second, getting privacy right will be key -- especially for teens -- for encouraging use of Live as a sharing tool rather than just for consumption." "The reality is, if a normal person broadcasts publicly, their friends will all get notified and that will be the majority of the audience they get. But they're explicitly deciding to share publicly, so they won't really mind if their parents, teachers or coworkers see them." "When people really want to share with their friends though, I wonder if their 'friends' audience is too big for content this raw. It feels like we'd be better off either encouraging them to make a new audience completely from scratch, or at a minimum automatically limiting it to people their age so it excludes parents, teachers, etc." "Finding a good privacy model is key to making this work for teens. If we don't do this, then even if the medium of live video sharing takes off, teens will eventually migrate to a different platform to do it. But on the plus side, if we build a new audience to enable people to do this here, then that audience could be useful for other forms of sharing across the service as well." "There is also an element of just following attractive people. A lot of the most popular accounts on Instagram and Snapchat are models or attractive celebrities, and people just spend a lot of time watching their clips and looking at them. A lot of the Explore behavior on Instagram today is this. We could enable some of this through 'fashion' or 'celebrities' topics, but for the long tail of gawking I could definitely see people spending lots of time browsing public Lives of people of their preferred gender/age around the world. And it wouldn't be creepy because the people broadcasting explicitly want to have people watching them.)"
