Fixed, I think. In sociable.php, I changed the URLs to the following which appear to be working just fine:

'Digg' => Array(
		'favicon' => 'digg.png',
		'url' => 'http://digg.com/submit?url=PERMALINK&title=TITLE',
	),

'Google' => Array (
		'favicon' => 'googlebookmark.png',
		'url' => 'http://www.google.com/bookmarks/mark?op=edit&bkmk=PERMALINK&title=TITLE&annotation=EXCERPT',
		'description' => 'Google Bookmarks'
	),

'Tumblr' => Array(
		'favicon' => 'tumblr.png',
		'url' => 'http://www.tumblr.com/share?v=3&u=PERMALINK&t=TITLE&s=EXCERPT',
	),
