The problem of course is the fact they don't know. (or if they do they don't care). The other issue lies in the fact that you can put something on the internet for the whole world to see before your those synapses fire that tell you something is a bad idea and then you just go with it. The fact is that technology is so accessible to everyone that we get to SEE more bad magic whereas these guys (and gals. They can suck too) would just sit at home in the mirror or go to their local magic club and be bad. They were just a danger to themselves locally. Now they can be aggravating globally.
Wanting to get feedback to improve is fine. Do that. For the love of Dr. Blight, don't post every little 45 second brain poop you think is "good". Remove yourself from the equation and ask, "Is this the best I can do?" and if the answer is "maybe" you might want to hold off hitting that upload button.
The internet is forever....
