Style of DMing, is not to be confused with skill of DMing. I was merely saying that my style of DMing has not changed a whole lot from how I DMed back in the day.
I did not change the way I DMed when I played 3rd edition, Pathfinder, or d20 as a whole, as there were elements of those games that I and those I have gamed with over the years, thought inferior to the older editions or felt that were just plain lacking in the systems entirely. It wasn't until 2012 that I just got fed up with the direction that Pathfinder had gone, and it made me realize that I should have just stuck with running 2nd edition; so I went back to playing that edition and have not looked back since.
As for the term "back in the day", well, while I realize that there were others playing D&D differently, I must say that anecdotally, I never encountered it personally (the internet being the sole exception), just lucky I guess...
