Yahoo is shutting down MyBlogLog, a service acquired by the company a few years ago, that lets you see who’s been visiting your blog. It’s been known for quite some time that it would happen, but users received an email today setting the date. It said: 

You have been identified as a customer of Yahoo! MyBlogLog. We will officially discontinue Yahoo! MyBlogLog effective May 24, 2011. Your agreement with Yahoo!, to the extent that it applies to the Yahoo! MyBlogLog, will terminate on May 24, 2011.

After May 24, 2011 your credit card will no longer be charged for premium services on MyBlogLog. We will refund you the unused portion of your subscription, if any. The refund will appear as a credit via the billing method we have on file for you. To make sure that your billing information is correct and up to date, visit https://billing.yahoo.com.

Cloudspace developed MyBlogLog in 2005, and in early 2007, it was acquired by Yahoo for over 10 million dollars.
