I was farting around on YouTube and came across a series of vlogs by DoctorFailure. He has a series of vlogs he hopes will allow people to "become better DMs." I've only watched the first one so far (about random tables), and it's pretty good. He rambles a bit, but his stories and ideas are pretty solid.
It doesn't hurt that he looks like a long, lost brother...
Here's the link to his profile.
