First off...the guy is funny, but I can't take his rambling and long pauses. If he could somehow condense his thoughts, I'd enjoy his stuff more.
Second...the sub level of nerd has always been around. I was heavy into AD&D in the early 90's and the level of nerd was always obvious. Call them what you will, but the filthy basement dwelling Morlocks have always been here. Nasty ass, filthy humans that are a shame to whatever community they're infecting. To make matters worse, they're often arrogant assholes which is mind blowing a obese, literally filthy, unemployed pile of human trash that lives scott free off of his parents wants to nerd out on you and cock flex is ridiculous knowledge on some topic or another. I'd steer clear of these people when I was in D&D and it wasn't a hard task. I was part of what I called the "charismatic nerds"...people that could function in society and carry on a normal conversation, and wash their ass and hair more that once a month. There's plenty of us to go around.
One side story, around 2006 or so, I met up with a guy from Chicago that wanted to do a game trade. He came down and we traded some wares. The motherfucker was easily 400lbs and literally spelled of old cigarettes and sun ripened side of beef. The house smelled so bad after he left that when my wife returned, she immediately picked up on the scent. The guy was that filthy. I have no idea how someone lives like that.
