This is actually a much more interesting question than I first thought. It depends on my mood. I can tolerate annoying voices, and droning voices, but a really good personality does add points. Begging me to hit buttons, no, just stop it. Absolutely hyperactive bouncing around and always spinning the camera just makes be want to barf. Sit the heck down and complete a sentence already. Sometimes I want a tutorial or a mod spotlight, and yes, it's usually on really obscure or new mods -- like Pinkly Sheep, I have yet to see someone try to explain the madness of it. Other times I want to see a build, and I can have hours of city building or nether fortress makeovers going on in the background. And some youtubers (oh, Squiddy) are just so dang funny together, that I can CrazyCraft with them any time, whatever they choose to do, or forget they were doing, it's like a friendly asylum over there. No problem going over some allotted time, I'm not keeping track, but also learn to cut away if something is going to be a snooze.
