????为何众人纷纷离开Twitter？这款产品风头正劲——现在每月有2.5亿条Twitter消息，而就在2010年9月才只有9,000万条。据Twitter首席执行官迪克?科斯特罗称，截至10月中旬，该公司市值约为80亿美元。一年之前，Twitter管理层经历大地震，创始人杰克?多西重返公司，担任产品开发主管，而科斯特罗则出任首席执行官。然而，震荡一年之后，仍不断有员工离去。

????离职的知名员工包括：

????——通讯部主管肖恩?加勒特于上周（11月9日）宣布辞职。他刚加入Twitter时还是光杆司令，而等到离开时，Twitter通讯部门已经有8名雇员。

????——工程部副总裁迈克?雅培于10月13日宣布将离开Twitter，作为入驻企业家加入风险投资公司基准投资（Benchmark Capital）。

????——首席科学家阿卜杜拉?肖博瑞证实他将离开Twitter，转投旧金山一家名为Alta Vista School的独立小学。该校于9月中旬由肖博瑞和他人一同创立。肖博瑞在此前负责实现Twitter的搜索推荐。

????——帕姆?克莱默在7月份被聘为Twitter首位负责消费者市场营销的副总裁，然而短短三个月后已经离职。

????——最近离开的是iOS应用程序Tweetie的开发者罗兰?布瑞特。他发布Twitter消息称：“今天是我在Twitter的最后一天。我准备花些时间来想想下一步怎么走。对于我们团队的发展，我感到由衷的自豪。”

????——该公司的两位初期风险投资人——风投机构USV的弗雷德?威尔逊和投资基金星火资本（Spark Capital）的毕贾?萨伯特——在9月中旬离开了董事会。

????当然，尚待解答的问题是，这些高层员工为什么离开？尽管该公司在飞速发展，但Twitter积重难返，杰西?亨普尔在《财富》杂志（Fortune）四月刊中列举的问题似乎仍然存在。

????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.
