Livestreaming is great if you can offer consistent value or entertainment (which itself is value). I think the best part of livestreaming is connecting with your most avid subscribers and give them some interaction that people normally wouldn't receive from people they follow. If you're trying to make money out of Superchat, then it's even more important to provide value. For me, I used superchat as a means for people to get their questions answered during my Q&A livestreams.
Acutally I was thinking of fan interaction down the road. For now I was thinking of making a video compilation of all my videos and streaming it live. Like all the funny cuts, and epic fail. I was wondering if that would work well.
If you think your audience will find it entertaining enough to watch, then it wouldn't hurt.
