I have been exploring the Hacker News API [0] a bit and came up with this simple way of exploring a user's past submissions including the comments [1].
It's been fun to dig through some of the old submissions and reading the comments, so I thought I'd share.

Caveat: For accounts with a lot of submissions, it may take a while to load.
