As someone who's had much less time to play video games, having Twitch streams and Giant Bomb content on in the background has replaced cable TV entirely, and I subscribe to Giant Bomb so it's not too much of a stretch to sub to a twitch channel, but rarely ever for more than a month or for more than one channel at a time.
Some people here don't seem to understand that Twitch is more than just someone streaming and someone watching, most streamers tend to develop a community within their channel, and if a streamer plays a game I like then the channel is a great place to talk to a bunch of people about that game, or get some insight about it from the streamer since he's probably played a ton of it. For the bigger streams this is pretty much nonexistent though since chat is mostly a complete shit show.
I'm all for people making a living playing video games, but reading out every donation and stopping to thank every subscriber seems to always attract the kind of people who get upset if their donation or subscription isn't noticed, and pandering to that kind of audience is usually what causes me to find another channel to watch. Speedrunners for the most part, while they do get a bit hostile about it sometimes, seem to have a good grasp of where the line is between making a living off of their passion and shamelessly begging for money.
