Cathie Black Resigns: Twitter Users React (TWEETS)

Cathie Black, we hardly knew you.

After just three months in office, the magazine executive turned New York City school chancellor has tendered her resignation as the city's top education official.

Mayor Bloomberg called Black into his office early Thursday morning, encouraging her to resign. The short tenure as chancellor had been a tumultuous one, and the mayor and black agreed change was necessary, according to The New York Times.

Black's approval rating had recently dipped to an abysmal 17 percent, leaving many in the media hardly surprised.

Forbes' Jeff Bercovici wrote:

As someone who covered Black, on and off, for nearly a decade during her career as a media executive, I’d have to say I’m even less surprised than most to see her go. The faults that turned her colleagues in government and the public against her — standoffishness, self-aggrandizement, a tendency to respond to every criticism with spin and wagon-circling, a pattern of rewarding loyalty rather than competence — were all on display during her tenure at Hearst for anyone who was looking.

Deputy Mayor Dennis Walcott will replace Black as school chancellor.

What does the Web have to say about all this? In a phrase: "That was fast."
