You'd think a media mogul as powerful as executive managing editor of The New York Times would own Twitter, but Jill Abramson is so bad at it that her kids make fun of her. "I don't keep up with Twitter all day long. I am just a beginner. My kids tell me how terrible my Tweets are. They give me a Twitter (grade of) F," she admitted at a media mixer, reports Market Watch. While true--she's only tweeted 21 times in three months--they should give their poor mother a break. She only joined the social media site a few months ago and we're guessing her plate is pretty full right now, learning the ropes of her new important job, and stuff.
