I'm in the process of moving my old self-hosted WordPress blog from my own server (which I'm repurposing) to Blogger.
First step is this - creating the blog and redirecting my domain - done.
I'm going to export, convert then import it - found a brilliant guide by +Marziah Karch - http://google.about.com/od/googleblogger/a/How-To-Move-Your-Blog-From-Wordpress-To-Blogger.htm
The actual tool to convert the blog data is this: http://wordpress2blogger.appspot.com/
So - more to come, when I get done with the conversion - probably during this weekend (maybe later - family things first).
Oh - and the (old) blog is mostly in Danish, but I'm going to change that in future posts - there'll be both Danish and English posts - just like on Google+
