Definitely easy to use, but once I was on the preview page for my image, I didn't see an easy link to share right now. Is the link I'm on shareable? I think there should be a few default sharing options (other than Twitter/Facebook) right on the page: link, e-mail, maybe SMS?

Edit: I see the Sociable buttons that include e-mail, this should be much more obvious. Still don't see an obvious "Copy this link".
