I have just deleted all my historical entries. I don't really want to find a way to import them; if they were going to be online, I'd want to read them first and do some cleanup work, discarding stuff I didn't feel should still be online and making sure the formatting was consistent.

That makes the project a fairly large one, and instead of doing it, I've been using the fact that I haven't done it as an excuse not to write new entries. That's bad behavior, and I'm putting a stop to it.
