I really only got into Twitch when Ryckert started streaming at the beginning of the pandemic. I've since found some other channels like Kyle Bosman and O'Dwyer's noclip. It really is just great background noise but a lot of the big streamers are kind of a turn off for me. I really just go for gaming media people that I know like O'Dwyer, Tamoor Hussain, Bakalar's pinball etc. and they usually are pretty entertaining.
I actually did start streaming a few months ago. I avg like 3-4 viewers and it's almost always my brothers and an old buddy who lives in a different state. It just scratches that itch of when I used watch my brothers play Resident Evil or vice versa when we were young. It's fun. I'm late 20s if that helps.
