When I worked at a couple magic shops in the late 90's and early 2000's I thought there was a lot of crap magic being released... but little did I know what was on the horizon. How could I have known that the way to be known in magic was to release a glut of mediocre products? Who could have forseen youtube making it so easy to self publish and sell something you "created" that day without research or real world practice?
It's a brand new world. Material is being released at the speed of thought and it shows no signs of stopping. If you think I am exaggerating, then look at places like the Latest and Greatest section on the Soylent Green or even all of the crap being sold and bought on facebook groups such as Surplus magic Exchange.
It makes the mind wobble.
