It’s April Fools’ Day — a day that the Internets is rapidly transforming from a day of “Kick Me” signs and “Is your refrigerator running?” prank calls to a day of sophisticated, multi-media offerings, where the likes of Google, NPR, and Twitter have at the ha-ha. TechCrunch has thoughtfully put up a page (being updated throughout the day) with all the jokes surfacing throughout the day. (And yes, Google has “introduced” smellable Internet today, in case you were wondering.)
