Except for the part where own3d was a terrible entity to do business with as a streamer (routinely late on payouts, etc).

I've always wondered why YouTube doesn't push seriously into the video game and eSport streaming business.

Most streamers have YouTube channels that they advertise on Twitch. YouTube is obviously massively popular, and could possible grant more audience to eSport streamers. YouTube has streaming, but it feels like a side-project.
