Backing up my HN comments?

I wonder if anyone has a good solution for backing up your Hacker News comments. I've posted a lot of comments, and I like a local archive of things like this when possible.

Clicking on the Comments link and following the links manually will eventually yield a bad link due to HN's closure timeout problem. I've not tried to automate it.. yet.

FWIW, I do this with github too; I wrote a tool that pulls all comments, issues, etc for a project, and commits them right into a github branch in that project. http://github.com/joeyh/github-backup
