So I stumbled on a great YouTube channel called Drunkens & Dragons a couple of weeks ago. I don't know much about him other than he goes by Hankerin' and he's awesome.
He's got some great insight into DMing and does outstanding game-related craft projects. I've watched most of his videos and I have to say, I've learned a few things. He has an off-beat sense of humor, but I think that's kind of required if you're gonna pretend to be a wizard or a barbarian for long periods of time.
Now go watch his vids and learn to play D&D like a big ol' bad ass!
