I never used Twitch before the pandemic -- watching people play games was never really my thing. But then I discovered the entire second use of Twitch, streaming music. Since March 2020, it's been possible to find someone streaming music at pretty much any time of day.
One day I was watching around 2am Pacific time, and the stream ended. I was looking for another one when I saw someone in the music category with 13,000 viewers (most DJs don't crack 1000). So I went to check it out.
It was a hot tub streamer holding a guitar while she thanked people for their tips and subs. In the 10 minutes I watched, she never once played anything.
I was fascinated by the fact that she had so many people basically just watching her in a hot tub and giving her money. She wasn't doing anything compelling.
To each their own, but I had no idea there were so many people on the internet willing to pay for such a thing.
