Ok so I thought the Google Map's April Fools joke was funny until I recently discovered Gmail Tap. There has been numerous complaints about how texting can be a problem in certain scenarios. What Gmail TAP does is it replaces the normal qwerty keyboard and fills it with a "dot" and a "line." The idea behind Google TAP is Morse code. It is Google's method to bring back a dying communication form. This video is a must see.
Getting back to topic, all these jokes and gimmicks that Google is posting today on April fools is a strategic method of social media. Even though these jokes are irrelevant/just for fun they bring a load of traffic to the Google website. This is truly a fun way to use social media to create a positive upon the Google branding.
