Why is everyone leaving Twitter? The product's growing more popular by the day -- it's now generating 250 million tweets, a jump from 90 million in September of 2010. As of mid-October, the company's value was some $8 billion, according to CEO Dick Costolo. And yet, a year after the management shakeup that put founder Jack Dorsey back into the chief product role and Costolo in the CEO spot, employees continue to leave.
Consider this:
-- Head of Communications, Sean Garrett announced his resignation last week, November 9th. When he arrived, the Twitter communications department went from zero people to eight by the time he left.
-- Mike Abbott, VP of Engineering, announced last month on October 13 that he would be leaving and moving to his a role as Entrepreneur in Residence at Benchmark Capital.
-- Chief Scientist, Abdur Chowbury, who was responsible for implementing Twitter's search recommendations, confirmed that he would be leaving to work on Alta Vista School, an independent San Francisco elementary school a co-founded in mid-September.
-- Pam Kramer, who was hired in July as Twitter's first VP for consumer marketing left the company after just three months.
-- One of the most recent departures is Loren Britcher's -- creator of iOS app Tweetie -- tweeted, "Today was my last day at Twitter. Taking some time to figure out what's next. Really proud of the way the team has grown."
-- Two of the company's first vc investors Fred Wilson of USV and Bijan Sabet of Spark Capital left the board in mid-September.
The unanswered question is, of course, why are the top employees leaving? Despite rocket growth, the trouble @ Twitter chronicled by Jessi Hempel in Fortune's April issue seems to be ongoing.
