probably not, twitch already has a lot of advertiser, viewer, and industry support. though from the sounds of things i don't know if i'm sure that they're planning on directly competing with twitch. steam's broadcasting was always a lot more focused on small streams with friends, cus that's where steam's strengths are, and i guess it sounds a lot like they're just planning on just streamlining viewing so it doesn't suck as much. but i guess we'll see, if they add nice discovery and community features for it maybe it could grow well enough.
