They really need to work on marketing and poaching youtubers but I am guessing devs want to have fully functional product before taking a shot at the big league . Anyway we are going for a long run and with crypto world expanding and showing stability we could see lbc in top 10 coins.All that is left for us is to increase our bag by trading on 2-5% coin price oscillation 
But why would youtubers come to this platform? Big youtubers makes good money and why would they start from the bottom again? It's great idea but I think it will be hard to get users because youtube is just youtube. Everyone knows youtube, people make good money on it, why would they go to other platform?
another income is better answer i think.
without leaving old platform, and joining new platform is great. as you know, writer will write anything in any platform he can write for income, right? so, by using LBRY platform they will get more income without leaving youtube
