Google’s first tweet was: “I’m 01100110 01100101 01100101 01101100 01101001 01101110 01100111 00100000 01101100 01110101 01100011 01101011 01111001 00001010."
Many of you probably recognize that language as binary code, and if you can read it...well, you're either a huge nerd or a robot. Decoding the message reveals the entire phrase to be "I'm Feeling Lucky" - which is the button next to the search button on the Google website! You've probably always wondered - what the heck is that button for, anyway? Yes, in the past we've told you about goofy "I'm Feeling Lucky" features such as the crazy Google gravity trick, but that is not its primary function. The button can actually be used to take a sort of a gamble on your web searching. If you have a great deal of faith in Google's search engine, you can click the "I'm Feeling Lucky" button and it will automatically take you to the top search result. It's kind of like a game of Russian roulette, but with FAR lower stakes!
Another fun fact: around 1% of all Google searches use the "I'm Feeling Lucky" button. Because searching this way bypasses the advertisements on Google's results page, the button has been estimated to cost the company around $110 million in revenue annually!
