Happy new year! I hope that Twitch will be able to take place of alphabet... I don't know what research you have done so it is hard to help you. Applaud (positive enforcement for creator) It would be great, creator could see what part of the show is most popular and the consumers could erxpress themself while limiting spam.
Why I watch YT and not Twitch (when I do) ... I can,t stop/fast forward live video :(
