As far as favourite streamers go, mine would be Cyberdemon531.

She's usually streaming very high level DooM and Mega Man speedruns, being a world record holder in both series. Some of her other speedruns are a little more eccentric and still a ton of fun to watch too. Not to mention the community surrounding her is very open and welcoming. I've been watching for a few months now and I'm still having a good time.

Also she's the only reason I'm even aware of DLive at all since she is always actively trying to help the platform grow by posting original videos and streaming (often for 8+ hours) on a daily basis. Her ability to be equally as attentive to the DLive chatroom as the other places she streams is a huge plus too, a trait which is surprisingly rare among the streamers I've seen on the site so far. It's kind of refreshing that my first stop to watch livestreams isn't twitch.tv any more.

Just in case anyone is interested you can find her here:
