I'm a "millennial", so I think I speak millennial pretty well. Twitch is a very niche product: THE go-to place for the gaming community, it's also trying to break into mainstream live-streaming but that's Instagram's territory.

Which is super interesting because twitch was justin.tv's pivot FROM mainstream live-streaming into the niche game streaming market

Yeah, I know ! Thing is, I think Justin is ahead of his time (he did it with Justin.tv and Whale).

Yeah but as more and more podcasters and talk show type youtubers start livestreaming on twitch to diversify income it'll get some more mainstream appeal.

Twitch is tiny compared to YT and growing slower.
