Curiosity Mars Rover arrives on Mars, tweets it
The good: After numerous attempts to get to Mars, the Curiosity Rover finally landed on the planet in August. From the surface of the Red Planet, the Rover tweeted: "I'm safely on the surface of Mars." But the expanded tweet was quickly retweeted -- more than 71,000 times in total -- just as it was exploited after it was meme'd after making a sexual innuendo about being "in" the Gale Crater.
"Way to cheapen the whole experience," said one reply.
Barack Obama scores second term, most retweeted status ever
The good: President Barack Obama scores a second term in the White House and in the space of a couple of hours, he smashes two Twitter records, one after the other. With just three words -- "Four more years" -- the President received more than 816,000 retweets in just a couple of days after he won the 2012 U.S. presidential election, after hours earlier smashing the same record with just a few thousand fewer retweets.
What did it? It was likely that adorable picture of the president hugging his wife, Michelle, which has received worldwide fame. On Facebook, the same picture has close to 4.43 million 'likes'. All in all, with 20 million tweets in total, Election Day became the most tweeted about event in U.S. political history, Twitter said.
Marissa Mayer hired as Yahoo CEO, awkwardly announces pregnancy
The good: In taking most high-powered jobs, one wouldn't want to announce a pregnancy in the same month, let alone the same day. New Yahoo chief executive Marissa Mayer did, though. Within minutes after announcing she had the job, she took to Twitter to announce that she and her husband were expecting a baby boy in the coming months.
The technology news world buzzed with excitement and let out a collective "squeee!" at the news. After overseeing the development of Google Maps and Google Earth, among others, her move to Yahoo was expected to reinvigorate life back into the ailing former Web giant. Mixed results so far, but not bad all in all.
