Who Is Programming the Birthday Emails From Facebook?

I am signed up to receive emails about friends with birthdays in the next week. It’s a neat service that usually works as expected. This week, the email showed a bit of a bug… can you spot it?

Whoops! facebook sorted Jan 2011 before Dec 2010

I believe that January 2011 should come after December 2010. Whoops! I guess amid the massive innovation, this corner case slipped through.

In any case, happy birthday to Dean and Steve :)
