How did Twitter's chief operating officer announce his resignation earlier this morning? Via tweet, of course.

"It's been an amazing ride, and I will cherish the memories," wrote Ali Rowghani, who initially joined the company in 2010 as CFO. The company's CEO, Dick Costolo, responded in kind:

The management shakeup within Twitter's top echelons was initially reported by Recode, which noted that Rowghani had failed to grow users and innovate the platform, and also that a recent stock sale of 300,000 shares for $9.9 million raised eyebrows.

Board members were also "chafed," per Recode, about a Wall Street Journal profile in April that referred to Rowghani as "Mr. Fix-It" and "co-CEO among employees."

Twitter confirmed Rowghani's resignation from the COO spot in an SEC filing today. "[He] will continue to be a Twitter employee and act as a strategic advisor to the CEO," the company said. "Twitter does not intend to hire a replacement for the COO role, and all of Mr. Rowghani's operating responsibilities will be assumed by other members of the Twitter management team."
