Good news! I've found out how to transfer the old blog posts to this blog intact with links and things.
Slightly less good news: They're all going to have the exact same date because I'm not transferring any metadata, just the posts themselves (because I literally just made new posts and c/p'd the content from the old posts to new posts)
Final news: While the links should still lead to the same places, the actual events I'm taking about in each post are long-since over.
...Also, it was interesting seeing where my head was only a year ago. Some of that stuff felt like it started a couple of years ago, not 12 months ago.
