Aha! Yes, I remember now, I must have seen jrnl here on HN. I certainly imitated its interface. Looking at the project again I'd recommend using jrnl instead of my one-off scripts, it's seen a lot of recent activity!
Now that my memory is jogged (amusing, for a journaling discussion), I opted for my solution because I wanted as few dependencies as possible for workflow reasons. Journaling is very personal, and I wanted the ability to quickly change the tool if it didn't suit me. Now that I better understand what I want, I may switch to jrnl. I also built a rudimentary task tracking system on top of my system as a separate tool, but that part really isn't worth sharing.
jrnl interop sounds useful, especially if bidirectional and automated (and for me personally, available on Android).
