I just hope we can continue seeing quality projects like Tarboy, Brackenwood, Fire and Ice - hell, even Foamy the Squirrel. In the past I've contributed what I felt were hi-quality projects on another account - and I earned some awards, but it didn't necessarily lead to greater things just yet.
I think as long as there's a potential for creators to expose their work to a larger audience via NG, it will continue bringing in talent, young and old. If we reward the people who contribute, dare I say, television or 'mainstream' quality work, or really just quality in general, I think you'll find several generations will continue to co-exist peacefully here.
I would honestly like to see the next Matt Groening, Trey Parker, or Seth MacFarlane hail from NewGrounds. Could be the next upload. And that's why I love it.
