Since Blogger are discontinuing FTP and SFTP publishing at the beginning of May, I've now migrated my blog to being hosted by a Blogger "custom domain", http://blog.peter-b.co.uk.
Fortunately, I've been able to use a .htaccess file to add a mod_alias Redirect directive that ensures that old links to http://peter-b.co.uk/blog/ will continue to work. So that makes it a lot less of a hassle!
What was a hassle was figuring out the CSS to disable the Blogger navbar, since it completely destroyed the harmony of my site design. It's hard to believe that it's almost seven years old! I should probably break out the text editor and update it at some point, but after this long I can hardly remember how to use CSS and HTML; I've got a lot of catching up to do.
