FOr other DM tips, you should look up Noah Antwiler's show, Counter Monkey.
He has some great DM advice and even player advice, and it's usually phrased in fun little stories of him and his friends playing together.
So I watched a bunch of his videos completely, gave it an honest try, and screw that guy. His lecture is verbose and aimless, he lacks charisma, and his opinions are pedantic and biased in a way that makes them useless. His front page has a 2-part review of D&D5 that's largely devoid of valuable content, and which is based on a read-through,
having never played the game himself, one of the cardinal sins of a reviewer.
I'm not saying a viewer couldn't get something useful out of watching his stuff. I'm saying you could get a dozen times the value from a
good content producer without feeling like you're slogging through a one-sided conversation with that boring guy who must tell you in detail how his Drow Ranger really pulled one over on those centaurs that one time.
Side note: some topics really are simple enough to say in text, and video or audio just slows down the absorption rate for the student, and is less efficient traffic-wise. Justifying video or audio requires presenting something that takes advantage of the medium, which he doesn't do.
Let's take his "Don't Split the Party" video. Here's what I would say on the topic:
1: Splitting the party is a common choice, but make sure you assess the risks associated with two or more smaller, weaker groups encountering the same dangers as they would as a whole group.
2: It also slows down the game, meaning less stuff gets done in total in the game session. You also have half the group watching, bored, at any time.
3: If you send a scout, make sure he doesn't go too far ahead or press his luck - his job is to look and listen and bring back information. The scout's job is essentially to ensure that the party isn't surprised, and that they surprise the monsters.
4: Assume your scout may get caught - don't load him up with equipment or story items.
5: If the scout (probably a Thief) steals stuff, the rest of the party will have grumblecakes about it, and bickering may result.
Please tell me you didn't take 25 minutes to read that, and that it wasn't as boring as listening to some dude drone on?
Finally, he uses Disqus for his comments rather than a simple RE-CAPTCHA, discouraging casual commentary.
TL;DR: Counter Monkey is low quality and not worth the time.
