Bloody Spam!
You'd think that not enough kids copy essays straight off the Internet, submit them, and then deny it when half the class submits exactly the same thing, not even slightly altered just to disguise the fact, and make the crib look personal!
It's the same malaise with almost anything, photography included. Start any topic and, almost at once, anyone can come back and quote this, that or the other without having had the slightest knowledge of the matter in hand even ten minutes earlier. It has reduced the value of experience and in-depth research (love) to a very low level, and as result, I believe that, in general, we are turning into a bunch of dumbed-down morons without a real, deep understanding of anything. Naturally, I tend to preclude those who learned their stuff prior to the Internet invasion; they had no alternative but to study, learn and try to remember.
