After reading the interview and many people's comments, this is one I'd like to add...
For me one big difference between the .Org community and YouTube is that, on YouTube, I get the overwhelming impression that people are watching and being all "Yay! AWSM!!" about most AMVs because they're fangasming over the anime IN the videos, not the videos themselves. This is how you get tons of terrible AMVs with tons of hits and glowing comments.
At the .Org, yes you still get this reaction to a certain degree, but that's not really an acceptable standard for evaluation around here. How much you like or don't like a series isn't supposed to be criteria by which you decide how good an AMV is, but on YouTube this seems to be the first (and often only) thing the average viewer cares about, in large part because it's built right into the YouTube system. You like cute little baby ducks? Here are some cute baby duck videos: "Awwww!! CUTE VIDEO!" You like DBZ? Here are some DBZ AMVs: "Wooo!! AWSM AMV!" Well thanks, but actually I had nothing to do with either of the things IN those videos...I just held the camera/combined some clips, but I get the feeling this wasn't what you care about, anyways. So...Cheers!
The .Org's standards of enjoying and evaluating AMVs fits very closely with my own, and it's why I don't pay much attention to what people say or think about the few videos I've uploaded to YouTube. I can't get there what I want, which is critical evaluation and appreciation of my AMVs. Yes, of course people saying they like my videos and are huge fans of X series gives me warm fuzzies, but at the end of the day I'm not making AMVs because that's the fire I'm trying to fuel. I'm very happy to leave that to the people who are much better at it, like Chiikaboom.
If I could make purely fan AMVs and be happy doing it, I'd probably be doing it, but I don't make those kinds of videos, so my happiness must needs come from other sources.
