You've just found out what Twitch is and how unbelievably big it is.
And your immediate reaction is that you just don't care.
I've been aware of Twitch for a few years but it still baffles me. What does it say about the state of the world that people can get rich from other people watching them play video games? (Don't answer that, I really don't want to know.)
I used to think that, but I've come to realise it's not all that different to all the watching-siblings-playing-computer-games we did as kids. A lot of the time I was more interested in seeing what came next in the game than I was in winning, and watching someone who was better at it was actually fine (even if the main motivation at the time was that there was only one computer and they wouldn't let you have a decent go).
The way I see it, Twitch makes about as much sense as podcasts
[1] or reality TV
[2].
[1] A radio programme about your niche interest, what's not to like?
[2] In which it's considered normal and ordinary for half the nation to spend hours watching randoms complete arbitrary tasks.
