Ask HN: Is there a way to get access to my comment voting history?

I tried to find a way to contact pg directly to ask him, but couldn't. Anyone know if this is possible? I'd like to analyze my personal voting record. I know I can find my saved stories, but would like to see voted upon comments as well.

At some point it would be interesting to get access to other people's voting records as well, but I hope that isn't easy to come by.

For those curious:

My goal is to look at whose comments I've been voting on, and overlay that information on their usernames whenever viewing comment threads. I want to give personal context to the users on HN. Essentially I want to mark commenters with my personal contributions to their karma.
