So what exactly is the allure of a Twitch Channel? I personally wouldn't find it interesting to be watching a streaming video of someone else gaming.
Just off the top of my head, I probably could think of more later.
1. Sometimes dev's will do previews of what's coming and show it off live. Yes you can always watch a youtube video of it, but depending on who is showing what, you can at least interact with the guys showing things off. For instance, one game I follow/play will do previews of their upcoming patches a few days beforehand. So you get the sneak peek, but also they take questions from people watching as well and will answer them. So it's at least a real time reaction/answer. This is personally my main reason for tuning in on twitch.
2. Maybe you are thinking about purchasing a certain game. Why read a review when you can just watch someone play it and decide for yourself. Yes, you could say, well you can just watch a video on Youtube, but it is a different experience. There's no showing an amazing bit of gameplay then cutting the bit where you derp your plane into the ground 20 seconds later. You can tailor a video in certain ways to make something like even better/worse than they really might be, where as on Twitch it's live, good, bad, boring, whatever, it's there, so in a way it's more of what you are likely to experience playing the game.
3. It's like a virtual couch. Before everything was online, I think a good number of us could remember going to a friends house to play games. Sometimes that consisted of just sitting and watching someone else play, maybe you were a younger sibling who never got a turn. Anyway, some folks enjoy watching someone else play games. In reality, is watching someone else play video games really all that different than watching someone else in a sporting event? I'm not arguing video games as sports here, just saying, when you break it down, the act of watching someone else do something is the same, you're not playing, just watching, etc.
I will say this though, it's certainly not for everyone and I do think that some game genre's are better suited than others to watch over twitch. Guess it just depends on what you're looking for and what you like.
