On the subject of DeviantArt, Stamper really said it best:
"As far as I saw, the "negative" reviews for this movie aren't as devastating as you made them out to be. They seem more like honesty to me. People on NG can be dicks, agreed - but they aren't like your DA people...primarily consisting of chubby girls addicted to Cowboy Bebop, Zelda, and Pocky - struggling daily to draw the perfect anime character with their "How to Draw Manga" book written by an American, so they can post their shitty and lopsided sketches all over their personal page. DeviantArt is a dumping ground. Everything is accepted, everyone has a nice and polite smile - because everyone there thinks they're an artist and needs respect and praise in return. NG is an entertainment site. We cater to millions of people, who watch, tell you what they think, and leave. That honest, that simple. Flash production, much like the video game industry, is growing at a rate so rapid that the bar is raised almost daily for production values, artwork, animation, humor, and more. Your bar is roughly 4 years lower, on all aforementioned subjects." -http://www.newgrounds.com/portal/view/3 15613 from his review here
Anyways, I agree with what Luis said. It has a reputation for sure, but the personal touch and interaction with a creative community is what brings me back.
