Hahaha, can't speak for the others, but I'm pretty sure I won't upload anything. In short, I'm not really artistic person. And I'm totally ok with that, to make it clear. I'm not even interested in drawing, I just like to watch other artist's works. I'm actually pretty sure there're quite a few DA users like me who never upload anything (maybe for different reasons, though) but are still kind of addicted to the site. Just like Youtube or Twitter, there're so many curious people checking it almost daily but never upload or write anything.
