Ah, okay.  That worked, but only partially.  I now have things displaying
okay when looking at any individual blog post (ie,
'blog/tony/2008/01/31/converted-site-drupal'), but not on the main blog
pages ('blog', 'blog/tony', etc.).  Apparently this is because those are
"views", not nodes, but I'm not really sure how to interact with a view
now.  To make things more complicated, it only makes sense to display this
stuff when everything belongs to the same user, so 'blog/tony' should show
the block, but not just 'blog'.
