When the Royal Baby is born later today, most of the Internet will be made up of one of two types of people: those that are really excited, and those that don't give a hoot, and would like to make that known. If you're the latter (you curmudgeonly soul!) The Guardian presents "Baby Blocker," a little addition to its site that lets you click "Not a Royalist" or "Republican" (it means something different in the U.K.) and get less coverage about the birth.
Looking to block all mentions of the baby from every single site you visit today? Maybe UnBaby.Me is more to your taste.
