I'm not so sure about the tiktok idea, but I just recently did start thinking about SN expanding to a YouTube type site. I have just gotten into fountain, and I thought that the reward/payment model for podcasts would translate nicely into video. I posted a question to SN members about Lightning Video, but got no response. I really think that a bitcoin based youtube alternative is necessary, especially as people (like me) start removing themselves from any Google products.
