I appreciate the new Blogger Importer in the latest version of WordPress, but what about a Blogger Exporter?
I don't really understand why someone would create a post in Blogger and then transfer it to WordPress. There's no way to have a category hierarchy that way. At least if you do it the other way around, creating the post in WordPress first, you can establish and maintain a category hierarchy in the WP post. Obviously, you would lose it to labels upon exporting the post to your Blogger weblog, but you'd still have the multilevel categories intact on your WordPress weblog.
So, a way to create posts with WordPress first and then export them to Blogger afterwards would be nice to have.
