Youtube has a strong interface + up and coming live streaming user base. Twitch has more streamers and viewers than Youtube Gaming but I feel the sorting algorithm is flawed when it comes to trying to find new content or a new streamer trying to gain following but I feel this could be fixed just by changin the search and sort algorithm.
We created a new Steemit supported live streaming platform: @vimm - https://www.vimm.tv/ We are currently in alpha state and to further test and refine it we need your feedback. We would really appreciate it if you could give it a try and give us your feedback through our discord: https://discord.gg/aR2RWGU
