What's interesting is that they're still only opening it for "partners", so they're not quite taking up the fight with Ustream, justin.tv or Niconicodouga yet.
Think if someone live streamed a suicide or some other horrible thing. On Justin.tv, Ustream that would be horrible enough, but on YouTube it would be a whole other level. I'm surprised it hasn't happened on one of those sites yet actually.
yeah, true -- this is all about scale. They have tons of online content producing partners that will be interested in doing live stuff, and also on the scale side of things, the YouTube reach is immense compared to the DIY streamer sites like justin.tv etc
