Edit: You can style ".hn-share-iframe". Then the next issue: it's much wider than it needs to be when the story has already been submitted (see the screenshot, there's a lot of blank space on the right). Is there any other solution besides just positioning it on the right of the share buttons list?
Unfortunately, not that I've found.. Twitter and G+ also reserve the space and run into the same problem. The root issue is the lack of automagic iframe resizing.. which is what "seamless" attribute will solve, once it arrives and is supported by the browsers.
