It being Saturday night, and me, having not much else better to do on Saturday night, decided to comment on Owen’s blog. I hadn’t noticed this before, but Owen has the WordPress favatars plugin installed. This plugin shows a favicon for a blog commenter if the commenter leaves a Web site URL.
This is what you’ll see in your logs when the favicon is being requested as a result of the plugin.
