????為何眾人紛紛離開Twitter？這款產品風頭正勁——現在每月有2.5億條Twitter消息，而就在2010年9月才只有9,000萬條。據Twitter首席執行官迪克?科斯特羅稱，截至10月中旬，該公司市值約為80億美元。一年之前，Twitter管理層經歷大地震，創始人杰克?多西重返公司，擔任產品開發主管，而科斯特羅則出任首席執行官。然而，震蕩一年之后，仍不斷有員工離去。

????離職的知名員工包括：

????——通訊部主管肖恩?加勒特于上周（11月9日）宣布辭職。他剛加入Twitter時還是光桿司令，而等到離開時，Twitter通訊部門已經有8名雇員。

????——工程部副總裁邁克?雅培于10月13日宣布將離開Twitter，作為入駐企業家加入風險投資公司基準投資（Benchmark Capital）。

????——首席科學家阿卜杜拉?肖博瑞證實他將離開Twitter，轉投舊金山一家名為Alta Vista School的獨立小學。該校于9月中旬由肖博瑞和他人一同創立。肖博瑞在此前負責實現Twitter的搜索推薦。

????——帕姆?克萊默在7月份被聘為Twitter首位負責消費者市場營銷的副總裁，然而短短三個月后已經離職。

????——最近離開的是iOS應用程序Tweetie的開發者羅蘭?布瑞特。他發布Twitter消息稱：“今天是我在Twitter的最后一天。我準備花些時間來想想下一步怎么走。對于我們團隊的發展，我感到由衷的自豪。”

????——該公司的兩位初期風險投資人——風投機構USV的弗雷德?威爾遜和投資基金星火資本（Spark Capital）的畢賈?薩伯特——在9月中旬離開了董事會。

????當然，尚待解答的問題是，這些高層員工為什么離開？盡管該公司在飛速發展，但Twitter積重難返，杰西?亨普爾在《財富》雜志（Fortune）四月刊中列舉的問題似乎仍然存在。

????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.
