Suggest to HN: fix upvote/downvote

The buttons for upvote / downvote in the comments are really close to each other. Sometimes I hestitate to hit the upvote button simply because I'm afraid I'll be hitting the downvote button instead. Does anyone else feel the same way? I really like the way Stackoverflow has upvote/downvote buttons - large, well spaced out, and with a clear visual indication of what you've voted on.
