"Steam.tv" accidentally went live today

A Valve representative told CNET that Steam.tv went live by accident, and was meant to be an internal test as of today: "We are working on updating Steam Broadcasting for the Main Event of The International, Dota 2's annual tournament. What people saw was a test feed that was inadvertently made public," said the company.

News outlets are speculating this could turn into competition with Amazon's Twitch and Mixxer. I don't see Twitch falling from the top spot anytime soon though. Amazon's gonna make sure of that.

Thoughts?

Update: http://blog.dota2.com/2018/08/the-main-event-with-new-steam-broadcasting/

First, we’ve integrated Steamworks support into broadcasting to allow us to tailor the viewing experience specifically to Dota 2: you’ll see markers for match starts, first bloods and team-fights populating the timeline as you watch live. We’ve also updated Steam Broadcasting with a new Live DVR feature, making rewind available as soon as you join the stream and allowing you to smoothly jump back and forth through the action. Combined with this custom Dota 2 Steamworks integration, you won’t miss a second of the action.

So it appears to be just a new way to watch the Dota event. Correction: As Tristar pointed out, Steam plans to extend Watch Party support to other games after the event's over, so that's good.
