Twitch sent out an email today, The email stated that they were going to be offering a new feature that would reduce the buffer so twitch broadcasters could broadcast with a smaller delay. If you've ever broadcasted on twitch you've experienced the delay that comes from the time that your viewers type a question, you respond to it and they get your response this is anywhere from 30 seconds to a minute.
lowering the delay could have a significant impact on a stream. Viewers might be more likely to stick around. Broadcasters could get feedback in real time. I know that I've been playing Minecraft and people in my stream are trying to talk me through a complicated process and there is a lot of trial and error because of the delay. In general more interactivity can only be a good thing. But it comes at a price.
That prce is less of a stream will be stored in a buffer on a viewers computer. So if they don't have the best internet access your stream may stop and stutter more often. At least with the delay you know what to expect. If your doing something particularly awesome in a game and the stream buffers at the wrong time the viewer is going to blame the streamer and they might not come back.
Honestly I don't know if I would turn this on or not. Would you?
