The case for Easter eggs and other treats

EVER ACTUALLY read a terms-and-conditions document? WordPress, a service for building websites whose clients include the White House and Disney, thinks anyone who has deserves congratulations. Its terms of service are the usual endless scroll of legalese, until you reach section 14, on disclaimers. Buried in the verbiage about warranties and non-infringement is a short, odd sentence: “If you’re reading this, here’s a treat.” Click on the link, and you see a picture of some appetising Texas brisket. Suitably revived, you can then move on to the stuff about jurisdictions and applicable law.Coming across an Easter egg, the name given to unexpected messages or features hidden somewhere in a product, is not like seeing funny advertising or following a humorous corporate social-media account. Easter eggs are winks, not gags; asides rather than stand-up.

But their defining characteristic is that they are playful.
