Twitch has been a success on PS4 what with 20% of streaming on the service coming via its users but now Xbox One is getting in on the action and providing a 'less limiting' experience than what Sony's offering does. Market speak you gotta love it, regardless this is a good thing as both consoles will now be providing their users the ability to stream the greatness or complete dire attempts at gaming for all to see and comment upon!
That's where things get interesting, no not the trolls or try-hards but the way developers can make the game react to what people are saying via the chat. Examples that are already in existence or are coming are the ability to give a player health, items or be evil and spawn more or powerful enemies for them to face. It's no longer a watch and that's it type thing, it's getting people involved and in a good way too. Of course you're going to have those people who try and push it but that's the world we are in today and except for the actions of a few dodgy blokes this will be a valuable feature for both consoles to have.
And being Xbox we of course have to have acheivements...
