Very pretty you might think - but it does mean that you can actually get some idea of Views rather than Subscribers (as read from the user agent string in the logs). Your logs will show every favicon read with the referrer "http://my.yahoo.com". It now shows up in my logs as my biggest referrer. Obviously most "referrals" are just picking up the icon but it does tell you how active those My Yahoo subscriptions are.
