Entertainment. Twitch is watched for entertainment and community. People in chat know and recognise each other, it's part of their daily routine. You can only watch so much of a guy just playing the game and doing call outs, it's boring as hell. Who wants to watch wishyouluck streaming 3v3 n using thorn for 9 hours. Triple complains nonstop, giggle just talks call outs 24/7. Broman doesn't appeal to me, and though I don't sub I do like to listen to goth when I play, and guys like holtzmann and slayerage are fountains of knowledge. I get that people watch to get better themselves, but at the end if the day it's entertainment, just like TV, and the popular streamers are popular for good reason.
