It's amazing how much Periscope got right in its design. I'm guessing scaling mobile video broadcasts was the limiting factor. If you're Arianna Grande going live just before she steps on stage, or BTS landing in the US for the first time or basically any rapper dragging Drake right now. There is no other experience that is simpler to use, more immediate, or more real for interacting with your followers than Instagram Live. Given 200M+ daily story users, the stream quality is technically remarkable.

Monetization for users with under 10K followers is much easier on Twitch.tv right now. Than on any other platform, including YouTube. The Fortnite cultural phenomenon is just beginning. And the ancillary revenue services such as Streamlabs involve direct sponsorship. As opposed to negotiating third party brand deals. Twitch popularity is creating the feedback loop that informs game design. Looking across the Pacific at Tencent and its 500M mobile gamers. Just can't help but think there is still phenomenal upside here ;)
