Don't get me wrong, I love YouTube. You can find a video of almost anything there, and if it's not there already, it probably will be soon. That's great. That's how modern entertainment should be - on demand, unfiltered and endless. However I'm not a fan of the apparent need people have to pick up a video in one place and publish it on YouTube sans the consent of the original creator.
Case-in-point, I looked up 'Mad World' on Youtube last week as a lark. I was quite surprised to find the flash collaboration I helped produce 5 years ago posted there in horrible quality by someone I've never met. He didn't take credit for it, but he also didn't even say where he got it from nor give credit to its creators. I'm rarely offended, but finding that video on YouTube with no credit to me or any of the other 24 contributors irked me.
It's not hard to contact me, either. All he would have to do is click my profile, send me a PM or e-mail, and ask. I probably would have been fine with it so long as he credited the source(s). It's that lack of courtesy that I think is the real problem with this kind of media. It's way too easy to simply take a video from one place and drop it into another site.

I see this all the time. Thinking that the average Youtuber has the mental capacity to assume what it took to make a Flash movie, is giving them WAY too much credit. But shouldn't they have figured it out by now? Taking stuff you "found on a site lollo" and not knowing or caring about who made it is awful. And the idiots in the comments are spouting "OMG HOW U MAEK THIS???"
But remember, you can place a copyright claim on your movies and make it so it can't be on Youtube unless YOU want it too, and then you can make the person uploading it give proper credit to you and this site. All you need to do is contact some Youtube administrators. Or something. All I know is that Egoraptor and Oney did this.
